Store description excerpt
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, read sheet music, 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. WHY CHOOSE SONID? Structured Curriculum: Follow an orderly map of music theory—from the musical alphabet to advanced modal harmony. A dedicated Sheet Music course teaches you to read notes, clefs, rhythm, and key signatures on the staff. Interactive Exercises: Practice intervals, chords, scales, and notation 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. Musical Playground: Visualize any scale, chord, or interval on a virtual fretboard, keyboard, or staff to see how the notes connect. Shared Assignments: Create a custom exercise and share it with a link or QR code. Teachers, students, and friends can take the same test—and you can follow their results. BUILD YOUR THEORETICAL KNOWLEDGE Every musician needs a strong foundation. Sonid gives you the tools to: Read Sheet Music: Learn treble and bass clef, note values, rests, meters, and rhythm so you can play from written music with confidence. Scale the Heights: Master every scale, from Major and Minor to exotic modes like Mixolydian and Phrygian. Bridge the Gaps: Learn intervals (the building blocks of music) to navigate your instrument with ease. Master Chords: Go beyond basic triads. Learn 7th chords, extensions, and jazz voicings. Understand Progressions: Learn why certain chords sound good together and how to create tension and release. FEATURES AT A GLANCE: Daily Guided Practice: Short sessions for intervals, ear training, chord construction, and sheet music. Level Up: Unlock new modules, earn XP, and collect badges as you progress. In-App Wiki: Instantly look up any musical term or concept without leaving your lesson.
