Everything moves together
Transposing is only useful if the chart follows the audio. Change the key and the chords, the tab and the notation are all rewritten to match what you are hearing.
Key
Transpose any song to a key that suits you
Songs are recorded in the key that suited the original singer. SheetMuse moves the whole song — audio, chords, tab and notation — to a key that suits you instead.
Find a range that works for the singer
A song two semitones down is often the difference between a vocal that strains and one that sits comfortably. Try keys against the actual recording rather than guessing from a chart.
Capo-friendly for guitarists
Shift the key to land on shapes you already know, or to match a capo position the rest of the band is playing.
