App Description
SONID: LEARN MUSIC THEORY & EAR TRAINING
Master music theory, master your instrument.
Sonid is the most comprehensive music theory app designed to take you from a total beginner to an advanced musician. Whether you want to write better songs, improvise with confidence, or train your ear, Sonid provides a clear, step-by-step path to musical mastery.
Unlike other apps that overwhelm you with information, Sonid focuses on single-subject learning. This structured approach ensures you master notes, intervals, and scales before moving on to complex jazz harmony and chord substitutions.

Interactive Exercises: Practice intervals, chords, and scales with fun, bite-sized lessons designed for daily consistency.
Ear Training: Develop a professional ear. Recognize chord qualities, inversions, and progressions just by listening.
Real-World Application: Learn how to use theory in your playing. Understand how a Dmaj7(#11) works and where to use the Lydian mode.
