Your score. Your coach. Side by side. Unfold iPhone Duo and give your music room to breathe. MozScore Duo keeps the score in view while Toots guides your next move: the hole to play, the breath direction and the slide, clearly displayed together. A MUSIC SPACE THAT UNFOLDS On the open display, the score and coach share two panels. Set Duo on a table for a score above and guidance below. Close the phone to find your current piece, session, coach and library in a compact home. The interface also adapts to other iPhone models and iPad. READ THE MUSIC. SEE THE GESTURE. • Scores and tablature for 12- or 16-hole chromatic harmonica. • Hole number, breath direction and slide shown beneath the notes. • Synchronised audio playback with adjustable tempo. • Accessible zoom controls and layouts that fit the available space. • Notation-only display for musicians who already read sheet music. TWO WAYS TO PRACTISE WITH TOOTS Listen to the score first to hear the passage. Then switch to the listening coach: model audio is muted and the microphone can analyse the notes you play. Microphone listening starts only when you choose to start it. An illustrated harmonica highlights the expected hole and shows whether to blow, draw or press the slide. Advice is based on the score and selected passage: slow down, prepare a breath change or work on one difficulty at a time. YOUR REPERTOIRE. YOUR PACE. Choose a piece from the library or import MusicXML, MIDI and MozScore files. Select a passage, adjust the tempo and repeat it in a loop. Your settings and sessions stay on your device. OPEN AND PLAY No account to create. Included scores, sounds and note analysis are available on your device. The microphone is used for listening coaching; reading and audio playback work without it. A score to show where to go. A coach for the next gesture. And the space of Duo to keep them together.
