Scorelio: Sheet Music Player

Scorelio is a simple sheet-music viewer that lets you read, listen to, and practice your scores from a single phone. Load a file, hit play, and follow the cursor as it moves across the staves.

■ Supported file formats

■ Key features
- Score rendering with orchestral playback
- Cursor that follows the music in real time
- Choose how the score moves: turn pages, or hold the playback position centred or left of centre
- Solfège syllables (movable do) under the notes, taken from the key signature and following changes of key
- Tap anywhere on the score to move the playhead there
- Per-part mute and solo
- Per-part volume and instrument (sound) selection
- Hide a part's staff to read only your own line (hidden parts keep playing)
- A-B repeat with beat-snapped in/out markers
- Raise the tempo each lap of an A-B repeat (step, ceiling, laps per speed)
- Tempo control (50-300 BPM)
- Count-in: one bar is counted before playback starts
- Metronome with selectable click sounds and downbeat/offbeat options
- Chord track: automatic backing that follows the chord symbols in the score, with selectable voicings
- Audio track: play your own backing or reference recording in sync with the score — it follows even when you change the tempo
- Jump to any measure or section
- Recent scores on the home screen — pick up where you left off
- Full-screen paper layout

■ Designed for practice
- Solo your own part to focus on it
- Mute your part and play along with the rest of the ensemble
- Switch instrument sounds to make a part easier to follow
- Loop a tricky section with A-B repeat until you nail it
- Start slow and let each lap raise the tempo until you are up to speed
- Read your own staff large while the rest of the ensemble keeps playing
- Check rhythm and harmony against the metronome and chord backing
- Import a backing track or reference recording and practice along with it
- Sight-read a new score with the solfège syllables to hear how the notes relate
