1. Welcome — What is Gradus?

Gradus — School of Music Composition is an interactive composition curriculum rooted in the classical tradition of counterpoint and composition, following the path of Johann Joseph Fux's Gradus ad Parnassum. Rather than teaching you to analyze other people's music, Gradus teaches you to write music of your own — from the very first lesson.

The curriculum spans ten stages, beginning with single-note melodies and advancing through counterpoint, harmony, fugue, and full orchestration. Along the way you have access to:

  • Maestro — a composition professor who answers questions and gives feedback on your compositions
  • Composition studios — interactive tools for writing and hearing your own music
  • Practice tools — ear training and sight reading exercises
  • Orchestra reference — deep-dive pages on every orchestral instrument
  • Library — curated score analysis and listening resources

All lessons are available to members. Sign in to access the full curriculum.

Tip:You do not need to read any theory before starting. Lesson 1 gives you everything you need. Begin there and work through the steps in order — each lesson builds on the last.
Start Lesson 1

3. The Lesson Curriculum

The curriculum is organized into ten stages of study. Each lesson builds directly on the previous one, so it is best to work through them in order.

Ten Stages of Study (49 Steps):

  • Stage I — Foundations (Steps 1–12): Notation, intervals, scales, rhythm, triads, overtone series, chord progressions, voice leading, first composition
  • Stage II — Counterpoint & Harmony (Steps 13–24): Seventh chords, species counterpoint (five species), score study, secondary dominants, modulation, orchestration by family, form, chamber ensemble capstone
  • Stage III — Advanced Harmony & Orchestration (Steps 25–37): Chromatic harmony, augmented sixths, instrument combinations, altered dominants, extended techniques, counterpoint in orchestral writing, film scoring, portfolio review
  • Stage IV — Mastery (Steps 38–49): Post-tonal harmony, advanced score study (Mahler, Ravel, Williams, Tchaikovsky), full symphonic technique, original orchestral composition, final portfolio

Using the Lesson Sidebar

Inside any lesson, a sidebar panel shows all lessons organized by stage. Completed lessons are marked with a checkmark. Your current lesson is highlighted.

  1. Open any lesson at /lessons/1
  2. The sidebar appears on the left (or collapses to a menu icon on mobile)
  3. Click any lesson title to jump directly to it
  4. Completed lessons show a gold checkmark — track your progress at a glance

Progress Tracking

Gradus automatically records each lesson you complete. Visit My Progress in the nav to see a full overview of your journey through the curriculum.

Tip:When you return to the site after signing in, the Lessons link in the nav bar will take you directly back to the last lesson you visited — no need to find your place manually.
Go to Lessons

4. Ask Maestro — Your Composition Professor

Maestro is your personal composition professor, available inside every lesson. You can ask Maestro any theory question, request feedback on a melody or exercise, or get help understanding a concept before moving on.

Opening the Chat

  1. Open any lesson page
  2. Find the Maestro panel at the bottom-right of the lesson (or scroll down)
  3. Click "Ask Maestro" to open the chat
  4. Type your question and press Enter
  5. Maestro will reply in the context of your current lesson

Getting Composition Feedback

You can describe a melody or exercise you wrote and ask Maestro to evaluate it. For example:

  • “I wrote a melody starting on C, going up to E, then down to D and back to C. Does it follow the rules for Lesson 3?”
  • “Why is a tritone leap considered bad in species counterpoint?”
  • “I'm stuck on the counterpoint exercise — can you give me a hint without telling me the answer?”

Auto-Feedback

Some lessons include an auto-feedback toggle that lets Maestro respond automatically when you submit a composition exercise. This is enabled by default. You can turn it off by clicking the toggle in the Maestro panel if you prefer to work independently.

Tip:Maestro works best when you ask specific questions. Instead of “Is this good?”, try “Does this melody have any awkward leaps or weak cadences?”

5. Young Learner Tools

Three colorful, age-appropriate composition tools designed for the youngest musicians (kid age mode). All three use real staff notation and VexFlow rendering to build musical associations early.

Rhythm Playground

Build rhythms by placing color-coded notes on a real treble clef staff.

  1. Go to Compose → Rhythm Playground in the nav bar
  2. Select a note duration: whole (purple), half (green), or quarter (orange)
  3. Click on the staff to place notes — each snaps to the nearest pitch line
  4. Watch the beat ruler fill with color-coded segments as you add notes
  5. Press Play to hear your rhythm with a click track underneath
  6. Use Undo to remove the last note, or Clear to start over
Tip:Kid mode offers whole, half, and quarter notes with 4-beat and 8-beat challenges.
Open Rhythm Playground

Melody Builder

Write your own melodies with guided step-by-step prompts and a rainbow piano keyboard.

  1. Go to Compose → Melody Builder in the nav bar
  2. Select a note duration from the color-coded buttons
  3. Click a rainbow piano key or click directly on the staff to add a note
  4. Follow the guided prompts — they suggest starting on C, moving by step, and ending on the home note
  5. Press Play to hear your melody, or Clear to start fresh
Tip:Kid mode uses the full octave (C4–C5) with all durations and teaches arch-shaped phrases.
Open Melody Builder

Echo Counterpoint

Write a second voice beneath a given melody and learn about consonance.

  1. Go to Compose → Echo Counterpoint in the nav bar
  2. A melody appears on the top staff — press Listen to hear it
  3. Click the rainbow piano keys to add notes to the bottom staff, one for each melody note
  4. Each note you place is color-coded: green (perfect consonance), blue (imperfect), or red (dissonant)
  5. When your counterpoint is complete, press Play Both to hear both voices together
  6. Try different cantus firmi using the melody selector buttons
Tip:Kid mode includes an interval reference card showing which intervals are consonant and dissonant. Aim for all green and blue — avoid red!
Open Echo Counterpoint

6. Beginner Sketchbook

The Beginner Sketchbook is a free-form composition workspace for writing simple single-voice melodies. It is the ideal place to practice the skills from Lessons 1–7 outside the structured exercises.

  1. Go to Compose → Beginner Sketchbook in the nav bar
  2. Click on the staff to place notes at the desired pitch and position
  3. Use the note duration buttons (whole, half, quarter, eighth) to set the note length before clicking
  4. Press the Play button to hear your melody through the built-in synthesizer
  5. Use the Erase button to remove individual notes
  6. Ask Maestro for feedback on your melody using the chat panel
Tip:The Beginner Sketchbook uses a treble clef in C major. Start by writing a 4-bar melody that begins and ends on C, as taught in the early lessons.
Open Beginner Sketchbook

6. Counterpoint Workshop

The Counterpoint Workshop is designed for the exercises introduced in Stage II of the curriculum. You write a counterpoint melody against a given cantus firmus (fixed melody), following the rules for each species.

Selecting a Species

  1. Open the Counterpoint Workshop from the Compose dropdown
  2. Use the species selector at the top to choose: First Species (note-against-note), Second Species (two notes per cantus note), Third Species (four notes), or Fourth Species (syncopation)
  3. The cantus firmus appears on the lower staff — this is the fixed melody you write against
  4. Add your counterpoint notes on the upper staff
  5. Toggle the Play button to hear both voices together

Daily Routine

Many students find it useful to treat counterpoint exercises as a daily practice — similar to scales or arpeggios on an instrument. Try writing one First Species exercise per day while working through Stage II. Speed and intuition develop through repetition.

Tip:If the Workshop flags a rule violation (parallel fifths, tritone leap, etc.), hover over the highlighted note to see an explanation. You can also ask Maestro to explain the rule in detail.
Open Counterpoint Workshop

7. Master Sketchbook

The Master Sketchbook is the most advanced composition studio. It supports multi-voice writing with up to four independent staves, and is intended for students working through Stage III and beyond.

  1. Go to Compose → Master Sketchbook
  2. Add voices using the "+ Voice" button (up to 4 staves)
  3. Select a voice to make it active — notes you add will go to that staff
  4. Use the duration buttons (whole, half, quarter, eighth, dotted) in the toolbar
  5. Switch between treble and bass clef per voice using the clef selector
  6. Press Play to hear all voices simultaneously in real time
  7. Use the tempo slider to adjust playback speed
Tip:If you are writing a four-part chorale (soprano, alto, tenor, bass), label each voice before starting — this makes it much easier to keep track of voice independence as the score grows.
Open Master Sketchbook

8. Import Score

The Master Sketchbook includes a MusicXML import feature that lets you load scores from external notation software (Finale, Sibelius, MuseScore, Dorico) for study and analysis.

  1. Open Compose → Master Sketchbook
  2. Click the Import button in the toolbar
  3. Select a .musicxml or .mxl file from your computer
  4. The score loads into the sketchbook where you can view, play back, and study it
Tip:MusicXML is the universal exchange format for music notation. Most notation programs can export to MusicXML via File → Export.
Open Master Sketchbook

9. Critique by Maestro

The Critique page lets you submit any composition — written in Gradus or exported from any notation software — and receive a structured, 32-point evaluation from Maestro. It is the primary composition feedback tool in Gradus.

Maestro evaluates your work across eight dimensions: Intent & Style, Melody, Rhythm, Harmony & Tonality, Voice Leading & Texture, Contrapuntal Craft, Unity & Variety, and Expression & Performance. Each dimension is scored 1–5 by a deterministic analyzer from the note data itself. Maestro then writes a narrative critique interpreting those scores.

Uploading a Score from Notation Software

  1. Export your score as MusicXML (.musicxml or .mxl) from MuseScore, Sibelius, Finale, or Dorico
  2. Go to Compose → Critique by Maestro
  3. Drag and drop your file onto the upload zone, or click to browse
  4. Gradus parses the score and shows a summary (parts, measures, key, time signature)
  5. Fill in the submission form: choose your style period, check the focus areas you want evaluated, and optionally describe your intent
  6. Submit — Maestro analyzes your composition and returns the full scorecard

Requesting a Critique from the Master Sketchbook

  1. Write or load a composition in the Master Sketchbook
  2. Click the ✦ Critique button in the toolbar
  3. Fill in the submission form and submit
  4. The scorecard appears in a panel above the score

Reading the Scorecard

The scorecard shows all 32 dimensions grouped by family. Each dimension has a 1–5 bar score (or N/A when the dimension does not apply to your composition). Below the score grid, Maestro identifies your three strongest dimensions, three areas for growth, and one concrete next step for your next practice session.

Tip:The critique is not automatic — you request it when you are ready. A short piece (4–8 bars) is enough for a useful evaluation. Longer pieces get more evidence per dimension.
Open Critique by Maestro

10. Practice Tools

Gradus includes a suite of practice tools for building fundamental musicianship skills alongside your composition work.

Practice Room

Your daily practice hub with a metronome, MIDI keyboard display, and spaced-retrieval review system. The metronome supports 7 time signatures, subdivisions, and tap tempo. The review system schedules concept review cards based on how well you remember them.

Open Practice Room

Ear Training

Four interactive modules: an interval library with famous song associations, an interval quiz with four difficulty levels, a chord quality quiz (major, minor, diminished, augmented), and a scale identification quiz (six scale types). Supports MIDI keyboard input for answers.

  1. Go to Practice → Ear Training in the nav bar
  2. Choose a module: Interval Library, Interval Quiz, Chord Quiz, or Scale Quiz
  3. Select difficulty, root note, direction, and timbre
  4. Press Play to hear the sound, then identify it
  5. Your score, streak, and accuracy are tracked per session

Sight Reading

A 10-level progressive sight-reading trainer. Three practice modes: pitch identification, timed flashcard, and interval recognition. Levels 9–10 include real Bach chorale excerpts. A Historical (Fétis) mode offers 22 progressive solfege exercises from Fétis's Solfèges Progressifs.

  1. Go to Practice → Sight Reading
  2. Choose a level (1–10) and practice mode
  3. Study the excerpt on the staff — rhythm, intervals, phrase shape
  4. Identify the notes or intervals as prompted
  5. Switch to Historical (Fétis) mode for graded melodic studies

Notation Quiz

Test your knowledge of musical notation terms with four quiz modes: selection, flashcard, multiple-choice, and matching. Filter by grade level (I–V) and category (tempo, dynamics, articulation, expression, ornaments, and more). Pairs with the full Notation Reference.

Take the Notation Quiz
Tip:Ear training and sight reading are most effective when practiced in short daily sessions (10–15 minutes) rather than long infrequent sessions. Build the habit alongside your lesson work.

11. Figured Bass & Chorale Harmonization

Figured Bass

Practice thoroughbass realization — reading figured bass symbols and constructing chords above a given bass line. Six historical collections of increasing difficulty are available:

  • Vidal — 178 graded exercises across 10 DEOs, from root-position triads through diminished sevenths (default)
  • Insanguine — 16 exercises with solutions (easiest historical set)
  • Handel — exercises with beginner and advanced solutions
  • Kellner — 48 graded exercises
  • Mozart — 24 exercises from Mozart's thoroughbass teachings
  • Ristori — advanced partimenti (most challenging)
  1. Go to Practice → Figured Bass
  2. Select a collection from the dropdown (start with Vidal or Insanguine)
  3. Read the figured bass numbers below each bass note — a reference table at the bottom explains all figures
  4. Click the staff or use the piano keyboard to place soprano, alto, and tenor notes above the bass
  5. Click a beat number above the staff to select that beat, or click directly on the staff
  6. Click a placed note to select it — use arrow keys to adjust pitch, Delete to remove
  7. Use the accidental buttons (♯ ♭ ♮) for chromatic notes
  8. Toggle "Show Solution" on collections that include one to check your work
Open Figured Bass

Chorale Harmonization

Harmonize soprano melodies from Bach-Schiorring chorales in four voices (SATB). Write alto, tenor, and bass parts, then check your harmonization against Bach's own solution. Each voice is color-coded for clarity. This develops voice-leading instincts and harmonic vocabulary.

  1. Go to Practice → Chorale Harmonization
  2. Select a chorale from the sidebar (filter by difficulty category)
  3. The soprano melody is given — select a voice (alto, tenor, or bass) to write
  4. Click the staff or use the piano keyboard to place notes at the correct pitch
  5. Click a beat number above the staff to select that beat for editing
  6. Click a placed note to select it — use arrow keys to adjust, Delete to remove
  7. Play back your harmonization to hear all four voices together
  8. Compare against Bach's original solution
Open Chorale Harmonization

Partimento

Partimento takes figured bass further: instead of realizing predetermined chords, you compose a complete piece from a bass line. Four progressive levels take you from fully figured realization to unfigured composition to imitative counterpoint over a bass — the method that trained the entire Baroque generation.

Open Figured Bass

12. Boulanger’s Harmonic Standards & Exercises

Nadia Boulanger's systematic approach to harmony, codified by Philip Lasser, lives in two places — one for reference, one for practice.

Boulanger’s Harmonic Standards (in the Library) — the read-only reference:

  • Principles — foundational axioms of tonal harmony with Boulanger's own quotes
  • Doubling Table — which notes to double in every chord type
  • Exercises — Boulanger's graded harmony exercises mapped to curriculum steps

Boulanger’s Exercises (in the Practice dropdown) — the interactive practice:

  • Voice a Chord — pick the four notes for each voice on the piano keyboard and check against the solution
  • Sing & Play — Boulanger's signature method: play three voices and sing the fourth (MIDI input supported)
Tip:Sing & Play is the crown jewel of the Boulanger method. If you have a MIDI keyboard, connect it and try singing one voice while playing the other three — it builds the deepest harmonic fluency. Reading the Standards is analysis; voicing chords and singing against three is the practice Nadia required.
Open Boulanger’s ExercisesOpen the Reference

13. Keyboard Harmony & Improvisation

Two advanced practice disciplines that build the deepest musical fluency — the kind where theory becomes instinct.

Keyboard Harmony

Following Nadia Boulanger’s method, keyboard harmony exercises progress through five levels: chord voicing in all keys, figured bass realization at the keyboard, transposition around the circle of fifths, melody harmonization, and the ultimate challenge — singing one voice while playing the other three. These exercises require a keyboard (MIDI or acoustic).

Open Keyboard Harmony

Classical Improvisation

Bach, Mozart, and Beethoven were legendary improvisers. These structured exercises restore the lost art: melody over a given bass, figured bass improvisation, melody continuation, theme and variations, and fugal improvisation. Start simple — even five minutes of daily improvisation builds fluency that written exercises alone cannot.

Open Improvisation Exercises

14. Score Study
