Hey everyone,

For our third workshop, we are moving away from strict, metric structures and diving into the wild, improvisatory world of the Baroque Toccata.

The word toccata comes from toccare, which means to touch. In the Baroque era, especially with North German composers like Buxtehude and a young J.S. Bach, a toccata was all about drama, rhetorical gestures, and making a fully written-out piece sound like it was being improvised on the spot. It is the ultimate showcase of the Stylus Phantasticus, or the fantastic style.

If you want to write one but are not sure where to start, here is a quick breakdown of how to put a classic Baroque toccata together, along with some great historical examples to study.

How to Build a Toccata

You do not need a rigid form here. Instead, think of it as a conversation that keeps changing directions. Try blending these four elements together:

1. The Dramatic Opening: Start with a burst of energy. Think rapid scales, broken chords, or unmeasured arpeggios that establish your home key before a steady rhythm even kicks in. For a classic example of this, look at the very beginning of Bach's Toccata and Fugue in D minor BWV 565, or the opening bars of Girolamo Frescobaldi's Toccata Prima from his first book of toccatas.
2. Pedal Points: Hold down a long, sustained note in the bass, usually the root or the fifth of your key, and let the upper voices weave fast, tense figurations over the top of it. A great example is the opening of Dieterich Buxtehude's Praeludium in C major BuxWV 137, where a long pedal note anchors a flurry of manual keyboard runs.
3. Harmonic Sequences: When you need to move the music forward, use a steady harmonic sequence like a circle of fifths to ground the piece and transition to a new section. You can see how this works in Bach's Toccata in E minor BWV 914, where structured sequences bridge the gap between free sections.
4. Sudden Breaks: Keep the listener on their toes. Let a flurry of fast notes come to a sudden halt on a weird, unexpected chord, leave a moment of silence, and then jump into a completely different texture. Michelangelo Rossi used this perfectly in his Toccata Settima, which is full of chromatic surprises and abrupt stylistic shifts.

This workshop will stay open indefinitely, so take your time with the writing. Let us know in the comments if you are planning to write something for this one so we can see who is on board. Happy composing! 

Let’s face it: modern conservatory training often treats 18th-century composition like a math equation rather than a living, breathing language.

We’ve all sat through harmony classes where a professor who mostly analyzes Schoenberg tries to explain how Bach or Durante thought. The result? Some incredibly bizarre, unhistorical "rules" passed down as gospel.

What is the single worst, most historically inaccurate piece of composition advice you were ever given by a modern teacher or textbook?

To start us off, here are a few classic offenders:

• "Never write parallel perfect fifths, even in inner voices." (Meanwhile, Italian partimento masters were hiding them in diminutions constantly).
• "Always write the melody first, then add the bass." (Fenaroli and Leo are turning in their graves).
• "You must resolve every dominant seventh down by step." (Tell that to the North German organ school).

Your Turn:
Drop the worst advice you’ve received in the comments below. Bonus points if you can name the historical treatise or rule that completely disproves it!

This canon is my favorite of the collection of 14 canons I'm currently working on. I really love baroque contrapuntual music and I'm trying to start from the base. Now this subreddit was created, I've thought it'd be a good place to share it. Any advice/opinion is welcome.

Hello everyone, and welcome to all of our new members! We have seen a massive surge of visitors over the last 24 hours, and we are incredibly excited to build this historical composition community together.

Whether you are an experienced composer, a music theory student, a keyboardist, or just someone who deeply appreciates 18th-century polyphony, we want to hear from you.

To help break the ice, please take a moment to introduce yourself in the comments below! Feel free to copy and paste these questions into your reply:

1. What is your musical background? (Are you a composer, an organist/pianist, a student, an engraver, or a listener?)
2. What notation tools do you use? (Do you prefer Dorico, MuseScore, Finale, LilyPond, or good old-fashioned manuscript paper?)
3. Who is your favorite Baroque composer, or what is your favorite piece of Baroque polyphony?(Give us a piece you never get tired of studying!)
4. What kind of workshops or mini-lessons would you like to see next? (Canons, dance suites, ornamentation, partimento realization, etc.)

Don't worry about being perfect or sharing sheet music just yet—this thread is completely informal. Drop a comment below, say hello to your fellow composers, and let's get the conversation started!

To ensure maximum structural precision in our ongoing 4-Voice Fugue Workshop, today’s lesson breaks down the strict mathematical rules of Invertible Counterpoint at the Octave.

When composing a countersubject, you are not just writing a melody that sounds good right now; you are writing a line that must remain grammatically perfect when flipped upside down later in the piece.

I. The Law of Inversion (The Rule of 9)

Invertible counterpoint is governed by a fixed mathematical constant: any original vertical interval and its inverted counterpoint interval will always equal 9.

Original Interval + Inverted Interval = 9

Because of this law, every interval transforms into a predictable counterpart when the lower voice is shifted up an octave:

• Unisons (1) invert to Octaves (8) — (Perfect Consonance to Perfect Consonance)
• Thirds (3) invert to Sixths (6) — (Imperfect Consonance to Imperfect Consonance)
• Fifths (5) invert to Fourths (4) — (Consonance to DISSONANCE)
• Seconds (2) invert to Sevenths (7) — (Dissonance to Dissonance)

II. The Absolute Structural Constraints

To guarantee your counterpoint is mathematically bulletproof and historically accurate to 18th-century conventions, you must apply the following structural rules based on the table above:

1. The Treatment of Imperfect Consonances (3rds and 6ths)

Because a 3rd transforms into a 6th (and vice versa), these intervals are completely stable in both positions. You can use parallel thirds or sixths safely, provided you change pitch direction after 3 or 4 consecutive steps to keep the voices linear and independent.

1. The Great Fugal Trap: The Perfect Fifth (5th to 4th)

In 18th-century polyphony, a vertical Perfect 5th is highly stable. However, the moment you invert the voices, that 5th becomes a Perfect 4th. In a two-voice texture, a Perfect 4th against the lowest active voice is classified as an unstable dissonance.

• The Rule: You cannot use an essential, un-prepared Perfect 5th on a strong metrical beat.
• The Exception: You may only use a 5th on a strong beat if it functions as a prepared suspension that resolves downward by a step, or if it is treated as a fleeting passing tone on a weak subdivision.

1. The Treatment of Dissonances (2nds and 7ths)

A 2nd inverts into a 7th. Since both are dissonances, they follow identical rules in both structural layouts: they must be prepared on a weak beat as a tying note, hit on a strong beat as a suspension, and resolve downward by step into an imperfect consonance.

III. Concrete Text-Notation Example

Here is a structurally bulletproof 2-measure fragment demonstrating inversion at the octave. Notice how every interval maps perfectly to the Rule of 9 without introducing illegal harmonies.

Principal Position (Voice 1 on top, Voice 2 on bottom):

• Beat 1: Voice 1: G4 | Voice 2: Eb4 -> Interval: 3rd (Consonant)
• Beat 2: Voice 1: F4 | Voice 2: D4 -> Interval: 3rd (Consonant)
• Beat 3: Voice 1: Eb4 | Voice 2: C4 -> Interval: 3rd (Consonant)
• Beat 4: Voice 1: D4 | Voice 2: B3 -> Interval: 3rd (Consonant)

Inverted Position (Voice 2 shifted up an octave, now on top):

• Beat 1: Voice 2: Eb5 | Voice 1: G4 -> Interval: 6th (Consonant)
• Beat 2: Voice 2: D5 | Voice 1: F4 -> Interval: 6th (Consonant)
• Beat 3: Voice 2: C5 | Voice 1: Eb4 -> Interval: 6th (Consonant)
• Beat 4: Voice 2: B4 | Voice 1: D4 -> Interval: 6th (Consonant)

For our next community initiative, we are shifting focus from complex imitative polyphony to vertical harmonic realizations and variation forms. We will construct a collective Chaconne based on a traditional Baroque ground bass loop.

This project emphasizes unfigured bass realization, motivic ornamentation, and historical voice-leading. Below is the foundational 4-measure pattern.

I. Structural Parameters and Metric Blueprint

Key and Mode: G Minor.

Meter: 3/4 (Standard triple meter for a Baroque Chaconne).

Form: Chaconne / Passacaglia (Continuous variation over an ostinato ground bass).

Texture: 3 Voices (Soprano, Alto, and Bass).

Linear Notation of the Ground Bass (Repeated Loop):

Voice 3 (Bass) — Ostinato Pattern (Measures 1 to 4):

Measure 1: G3 (Dotted half note)

Measure 2: F3 (Dotted half note)

Measure 3: Eb3 (Dotted half note)

Measure 4: D3 (Dotted half note)

Analytical Note: This is a classic descending tetrachord bassline (G - F - Eb - D), a staple harmonic sequence in the 17th and 18th centuries.

II. Technical Contribution Directives

Open your engraving software (such as Dorico, MuseScore, or LilyPond) and select one of the following structural variation tiers to post in the comments section below.

1. Tier I: Simple Chordal Realization (Basic Harmony)

Assignment: Provide a clean, three-voice texture by writing the Soprano and Alto notes that sit directly above the bassline.

Constraints: Follow strict voice-leading rules (no parallel fifths or octaves). Use standard Baroque root position and first inversion choices over the stepping bass scale.

1. Tier II: Melodic Diminutions (Ornamented Variation)

Assignment: Keep the basic chord structure but transform the Soprano line into an elegant solo variation.

Constraints: Introduce active rhythmic figurations. Use passing tones, neighbor tones, or traditional 7-6 suspensions on the strong beats to decorate the line.

1. Tier III: Textural Rhythmic Variation

Assignment: Realize the entire 4-measure phrase using a specific rhythmic pattern across the upper voices.

Constraints: Use techniques like continuous eighth-note arpeggios, standard French court rhythmic styles (dotted quarter followed by an eighth), or block-chord syncopations.

III. Submission Protocols

To maintain a clean and helpful comment section, format your entry as follows:

Technical Format: Paste your work using standard alphanumeric text notation (including octave markers like G3, Bb4), a direct link to an image of your engraved score sheet, or a link to a cloud audio render (SoundCloud/Drive).

Analytical Narrative: Briefly list the chord progression you intended (for example: i - VII - VI - V) and mention any suspensions you prepared.

This collaborative workshop initiates our community’s technical analysis and composition series. The objective is to construct an academically rigorous, four-voice fugue adhering strictly to 18th-century North German polyphonic conventions.

Below are the architectural parameters, metric configurations, and linear contours for the opening of the Exposition. Contributors must maintain strict historical voice-leading principles, including the preparation and resolution of suspensions, proper management of voice crossings, and the absolute avoidance of parallel or hidden perfect intervals.

I. Structural Parameters and Metric Blueprint

• Key and Mode: C Minor (Tonic) to G Minor (Dominant Minor).
• Meter: 4/4 (Common Time).
• Harmonic Rhythm: Anticipated at the half-note or quarter-note level, depending on contrapuntal density.
• Voice Disposition: Soprano (Voice 1), Alto (Voice 2), Tenor (Voice 3), Bass (Voice 4).

Linear Notation of the Expository Materials (Note Names and Durations):

• Voice 2 (Alto) — Subject (Measures 1 to 2):
  • Measure 1: C4 (Quarter note) - D4 (Quarter note) - Eb4 (Quarter note) - B3 (Quarter note)
  • Measure 2: C4 (Half note) - G4 (Half note)
  • Analytical Note: The subject features a minor-third ascent followed by a diminished-third descent to the leading tone (B natural), resolving back to the tonic before leaping to the dominant anchor (G4).
• Voice 1 (Soprano) — Tonal Answer (Measures 3 to 4):
  • Measure 3: G4 (Quarter note) - A4 (Quarter note) - Bb4 (Quarter note) - F#4 (Quarter note)
  • Measure 4: G4 (Half note) - D5 (Half note)
  • Analytical Note: This is a tonal/real adaptation transposed to the dominant hexachord. The F#4 functions as the secondary leading tone pointing toward the G minor tonal center.

II. Technical Contribution Directives

Please input this exact data into your music notation software (such as MuseScore, Dorico, Finale, or LilyPond) and submit your solution for one of the following structural components in the comments section below.

1. Invertible Countersubject 1

• Assignment: Compose the primary companion linear voice for Voice 2 (Alto) to run concurrently against Voice 1’s (Soprano) Answer in measures 3 to 4.
• Constraints: Must achieve strict harmonic validity at the octave or twelfth to ensure invertibility during later developments. It should employ active rhythmic contrast—preferably utilizing running eighth-note syncopations, suspension chains (7-6 or 4-3), or oblique motion to offset the quarter-note pulse of the Answer.

1. Modulatory Codetta (Link Passage)

• Assignment: Draft a precise, one-measure transitional link (Measure 5) immediately following the conclusion of the Soprano Answer.
• Constraints: This unit must utilize sequential melodic motifs (derived from the Subject or Countersubject 1) to smoothly modulate the harmonic center from the dominant minor (G minor) back to the tonic (C minor) to prepare the third voice entry. The texture must remain strictly two-voiced here.

1. Tenor Voice Entry (Voice 3)

• Assignment: Calculate and arrange the entry of the third voice (Tenor, initializing on either C3 or G3 depending on your codetta's resolution) in measures 6 to 7.
• Constraints: You must concurrently manage the voice-leading of the upper two active voices (Soprano and Alto). The Alto will transition to Countersubject 2, while the Soprano assumes Countersubject 1. Maintain strict voice spacing, rarely exceeding an octave between upper voices.

1. Bass Voice Entry (Voice 4) and Exposition Coda

• Assignment: Engineer the final entry of the exposition in the Bass register (C2 or C3), driving the texture into a full four-voice web.
• Constraints: This entry must solidify the tonic key, resolve all preceding linear motion, and provide a seamless contrapuntal exit strategy into the first Episode.

III. Academic Submission Protocols

To ensure constructive peer review, please format your comments using the following parameters:

• Technical Format: Paste your work via clear alphanumeric note text (with octave indicators), an image link to your engraved score fragment, or a cloud audio link (such as SoundCloud or Google Drive).
• Analytical Narrative: Append a brief breakdown explaining your handling of vertical intervals on strong beats, treatment of accented passing tones, and resolution of dissonance.
