Jniz is an open-source software tool designed to help musicians and composers build, analyze, and test complex chord progressions according to the rules of classical harmony and counterpoint. It acts as an interactive harmony assistant, automatically checking your piece for voice-leading errors like parallel fifths or octaves.
Here is how you can use Jniz to build complex chord progressions. 1. Set Up Your Project Base
Before adding complex chords, you must define the structural framework of your piece.
Choose a Key Signature: Select your home key (e.g., C minor or E major) in the project settings.
Select the Mode: Choose between major, natural minor, harmonic minor, or melodic minor scales.
Set the Time Signature: Input your meter (e.g., ⁄4, ⁄4, or ⁄8) to establish the rhythmic grid.
Define Voice Count: Select how many voices you want to write for (typically 4 voices for standard chorale harmony: Soprano, Alto, Tenor, Bass). 2. Input the Base Progressions
You can build your progression by entering notes or chord symbols directly into the software.
Melody First Method: Enter a soprano melody line. Jniz will help you find harmonizations that fit.
Bassline First Method: Input a bass progression. This is often easier for building specific chord structures.
Roman Numeral Input: Use standard harmonic analysis symbols (I, IV, V, vi) to quickly map out a basic chord backbone. 3. Introduce Complexity and Color
Once your basic progression is down, use Jniz’s tools to upgrade standard triads into complex chords.
Add Chord Extensions: Modify standard chords into 7th, 9th, or 11th chords by adding upper-register notes.
Use Inversions: Change the bass note of your chords (using first or second inversions) to create a smoother, more step-wise bassline.
Apply Altered Chords: Introduce secondary dominants (e.g., V of V) or borrowed chords from parallel keys (modal mixture) to create unexpected harmonic shifts. 4. Utilize the Real-Time Harmony Engine
The core power of Jniz lies in its automated constraint solver, which ensures your complex progressions still sound smooth and cohesive.
Run Rules Check: Click the analysis tool to scan your progression.
Identify Errors: Look for the visual markers. Jniz highlights illegal parallel intervals, forbidden leaps, or improper resolutions.
Use Suggestion Tools: If you are stuck on a complex transition, ask Jniz to generate valid chord options that mathematically satisfy voice-leading rules based on your current notes. 5. Export and Refine
After building and validating your progression, move it into your production workflow.
Listen Back: Use the built-in MIDI playback engine to hear how the complex voices interact.
Export MIDI: Export the progression as a MIDI file to drag and drop into your Digital Audio Workstation (DAW) like Ableton, Logic, or FL Studio.
Export Sheet Music: Export your progression as MusicXML to open it in notation software like MuseScore, Sibelius, or Finale. To help tailor this, let me know:
What genre of music (e.g., classical, jazz, cinematic) are you trying to compose?
Do you prefer starting your workflow with a melody line or a bassline?
