Reference
Library
This page explains the musical material used in the trainer: the interval targets, the registered voicing shapes, and the focus groups that narrow practice. It is a study reference for checking what each exercise is asking you to hear or build.
Intervals
Ear-training targets measured from a starting note. These are pitch-distance drills, not full chord shapes.
Voicings
Compact keyboard shapes used in voicing modes. Each item shows the harmonic family, density, register, chord degrees, and why the shape is included.
Categories
Filters for limiting a session to one harmonic family, texture, or voicing behavior.
Tracking
History
History is still lightweight at this stage. The trainer currently tracks the live streak during a session, but deeper attempt logging, weak-spot analysis, and review history are still in development.
Planned
Attempt history, missed structures, retry patterns, and review prompts.
Direction
Session summaries and targeted review based on where recall or construction breaks down.
Configuration
System
This is a technical notes page for the trainer. It documents how playback, input, and practice scope are handled, so a reviewer can understand the system without using the exercise screen.
Playback
Browser-based reference playback using four local Rhodes WAV samples, with gain staging, low-register protection, high-pass filtering, and a synth fallback when samples are unavailable.
Input
Interval mode uses pitch-class buttons. Voicing modes use registered note buttons grouped by octave, so answers must match the displayed chord tones and octave range.
Behavior
Scope filters limit the practice pool by musical role: rootless, quartal, sus, altered, dominant color, sparse, medium-density, and upper-cluster shapes.
