The transposition feature allows you to change the key of the music to match your instrument or vocal range. Not all
scores can be transposed - if the Transposition button is enabled on the Scorch or Avid toolbar you can click it to view
and select transpostion options. If the Transposition button is disabled or greyed out, the score cannot be transposed.

To transpose your music into a different key using the Avid viewer, click the 'Transpose' button on the Avid toolbar, as shown below.
