A file with your details, practice history, pieces and results, in a format other apps can read (JSON).

Each practice session is recorded against the instrument you played. Your main instrument is used unless you pick another when you add a session.

Adding a band is private to you: it is who you can say a rehearsal or performance was with. To share a band's music, open its menu and choose Set up sharing - or ask the band's organiser to invite you.

These are names you have logged rehearsals or performances with. Tap each one and say what it is - you are only asked once.

Invite someone to The Music Ledger. They get an email with a link to choose a password - it works once, for 7 days.

Tell them to look in their junk folder. The email comes from themusicledgerapp@gmail.com and will probably land there.

The grade lists in Scales and the grades in Theory follow the syllabuses published by ABRSM (the Associated Board of the Royal Schools of Music). The Music Ledger is an independent app: it isn't affiliated with, endorsed by or approved by ABRSM. Exam requirements belong to ABRSM and can change, so always check the current syllabus at abrsm.orgopen_in_new before an exam.

What goes in each block?

Here's your session

Tap any block to swap it.

Stretch your range a note at a time: play the scale to your comfortable note, then hold the next one as long as you can. Hold it for 8 beats three goes in a row to reach Level 5.

Pick a rhythm, then tap it - or clap, sing or play it - along with the click. Each rhythm has five Levels, each a little faster: play it well at a Level's speed to reach it.

The skills you're working on. Each one goes step by step through its tool: Tempo, Pulse, Pitch and Rhythm move you on at grade 4 or 5; for Warm-ups and Scales you say when you've got it; Range moves on when you move your range. Skills blocks in a practice session take the one you practised longest ago.

What a practice session's Warm-up blocks play. Pick one when you plan a session.

How fast can you play it through?

Pick a speed you can get to the end at. It's fine to go slow!

After the last bar you'll paint the bars that went wrong.

Cut it into focus bits

Each bit has to fit 5 goes in a block (4½ minutes, with a gap bar between goes). Tap the bar where a new bit should start; tap it again to join it back up.

A whole rehearsal in one file. Upload it here, then give it to each piece that is in it. The file is kept once; each piece remembers where it starts and ends.

How to record a rehearsal: use your phone's own voice recorder - it keeps going when the screen locks. Put the phone where it can hear the whole band. Use the ordinary quality setting, not "lossless". Upload on wifi. Tell the band it is being recorded. If anyone in it is under 16, a parent needs to have agreed - as for a photograph. Sound only: a video can't be added here.

Get a piece ready to practise: play it through, mark how each bar went, and cut it into bits to work on. Pick a piece to start.

How do you want to make it?

Short quizzes to learn music theory. Pick one, choose how hard, and see how many you can get right.

Short drills for your ear and your sense of time. Pick one, choose how hard, and see what Level you reach.

You're given a speed - a metronome mark, or just its Italian name - and tap it on the pad. Five speeds a round.

The click goes silent and you keep the beat going by tapping every beat - heard or not. When it comes back, see if you were still with it.

A note plays and you name it. Ten notes a round.
