Fifths is built around one idea: practicing against moving drone progressions, not just a single static tone. Create looping note sequences and changing tonal centers to work on intonation, improvisation, fretboard awareness, phrasing, and hearing harmony in motion. When you want a fixed reference instead, Fifths also works as a focused single-note drone. Use Fifths to: - Build looping drone progressions for scale, melody, and improvisation practice - Create single-note or multi-note drone steps to outline changing harmonic centers - Hold a single drone when you want a stable key center for ear training or intonation work - Explore the circle of fifths visually and hear key relationships instantly - See key signatures, relative keys, parallel keys, and scale notes at a glance - Train faster with daily questions, streaks, and multiple quiz difficulties - Add the Music Theory Daily widget to keep a fresh question on your Home Screen - Practice with 100+ sounds including strings, choir, organ, guitar, winds, pads, and synth textures - Save presets, favorite sounds, and tailor the app to your workflow - Customize note naming, reference pitch, octave range, fade time, and quiz length - Keep practicing alongside other audio apps Fifths Pro unlocks longer drone progressions, the full sound library, and Medium and Hard quiz difficulty. Whether you are working on intonation, improvisation, key signatures, modes, intervals, or general musicianship, Fifths gives you a practice tool that is immediate, musical, and built for repetition.
