About
OnKey – Scale Practice is a musician-focused exercise generator designed to streamline daily practice routines. Instead of flipping through method books or writing out scales manually, users simply enter a few basic parameters and OnKey instantly outputs the notes for their exercise. This keeps the focus on the *how* of playing rather than the *what*, making practice sessions more efficient and intentional. The platform includes several companion tools: **Practice Flashcards**, a free app that displays rotating tonic names on a configurable interval so musicians can practice scales, chords, licks, or harmonic progressions in any key; **UpBeat Metronome**, a free metronome with an upright-pendulum visual to help internalize downbeats and upbeats; and an **OnKey Spotify playlist** featuring long-tone drone tracks ideal for intonation and scale practice. OnKey Lite, the free version, is available on the web, iOS App Store, and Google Play, making it accessible across devices. The tool is suitable for beginners learning their first scales as well as advanced musicians looking to systematize their practice across all 12 keys. Music students, private instructors, and self-taught players will all find value in its straightforward, parameter-driven approach to exercise generation.
