Why can I only see the first page of the music?

We show you the first page of any piece of music so that you can be assured that the piece you're buying is indeed the piece you want. However, to see additional pages, the piece must be purchased. Once you purchase a piece of sheet music, you will be able to view, interact with and download all of the pages.

Why does my preview page show a Sample page instead of the first page of music?

Music that is only one page long may only show half of the page as a preview. The purchased sheet will print out this "Sample" page followed by the actual music. If you wish to view your purchased song online, you will be able view the music by logging into your account and accessing that order.

Why can I only hear a portion of the sheet music?

Prior to a purchase being made, due to copyright restrictions, we are only allowed to play a sample excerpt of copyrighted sheet music titles.

Why do I lose transpositions I make in the piece when I move off the page?

Transpositions will not persist past the page on which they were made. That is because a transposition takes place solely within the webpage, and each music file is read-only. If you transpose a piece while first viewing it, then decide to buy it, when you come back to the piece of music to print it, you must redo your transposition.

Why can't I transpose this music?

Only Interactive pieces are transposable. To transpose, click the Transpose Key or Transpose Instrument buttons in the tool bar above the piece.
