ClefMastery helps you build fluency in treble, bass, alto, and tenor clefs through quiz-style practice, scales, and arpeggios. Whether you’re a student, instrumentalist, or vocalist, you can strengthen note recognition and sight reading. Practice Your Way β€’ Tap to answer: Choose the correct note name by tapping a button. β€’ Play to answer: Use your instrument or voice; real-time pitch detection recognizes your notes! Scales & Arpeggios β€’ Scales: Practice major, natural minor, harmonic minor, and melodic minor. Choose root note, direction (ascending, descending, or both), and octaves. β€’ Arpeggios: Build custom chord lists with major, minor, diminished, augmented, and 7th chords. Pick root, quality, inversion, and direction. Chord labels on the staff show your progress through each pattern. β€’ Scales and arpeggios require answering with your instrument or voice (no note buttons). All Four Clefs β€’ Viola player? Cello player? No worries. We have alto and tenor clefs! β€’ Practice treble, bass, alto, and tenor clefs separately or together in realistic scenarios. β€’ Key signatures from the full Circle of Fifths are supported, so you learn correct spellings in any key. Built for Musicians β€’ Instrument presets: Quickly choose from violin, cello, piano, voice, and other instruments to set your ranges. β€’ Flexible settings: Instrument not in the presets? No worries. Just choose your note range and any transposition! β€’ USB and external mics: Use your external audio interfaces with ease. β€’ Pitch tolerance: Adjust sensitivity for fretless instruments and vibrato. You control how precise you have to be. β€’ Audio hints: Optional reference tones when you’re stuck. β€’ Intelligent sequencing: We plan the quiz intelligently to move around in pitch without making you do massive shifts on your instrument, yet still cover the full range. Stay Motivated β€’ Badges will highlight when you reach milestones! β€’ Stats: Track accuracy, problem notes, and progress over time. β€’ iCloud sync: History, stats, and settings sync across your Apple devices (iPad, iPhone, and MacOS apps).
