The OnlineSheetMusic Viewer is a powerful tool that you can use to transpose your sheet music by key, instrument, clef, or interval. You can find a short Transposition Tutorial video here:
After you have purchased the products you need and installed the Viewer, select the song you want to transpose from the Score List on the left side of the Viewer. Then, open the transposition menu by clicking the transposition button:
Transposing by key:
From the 2nd dropdown menu showing C Major/A minor, select a key and choose either Up or Down to indicate the direction of the transposition. For best results, when transposing by key, choose the direction which results in the smallest interval change. Click OK to complete the transposition.
To return to the original key, click Reload. Transpositions cannot be saved. Closing the selection or the Viewer will automatically reset to the original key.
Transposing for an Instrument:
From the 1st dropdown menu, select: For a transposing instrument. From the 2nd dropdown menu, now show Soprano Saxophone, select your instrument.
With a Piano Vocal sheet, you may want to transpose only the melody by selecting Staff Number(s) 1 through 1. You will transpose only the melody for the instrument you choose, and the piano will remain in its correct key.
Once you have transposed the melody line for a specific instrument, you may choose to change the octave of just the melody line. For example, Tenor Saxophone transposes up an octave and a 2nd, and the resulting transposition may be too high for the instrument. From the 1st dropdown menu, select By Interval. From the 2nd dropdown menu now showing Minor Second, select Perfect Octave. Select the Down button, and to transpose only the melody line select Staff Number(s) (Staff number 1 through 1 is the melody line). Click OK to complete the transposition.
Transposing by Clef:
You can change the clef on any staff by selecting Change to the following Clef from the 1st dropdown menu. Select the clef of your choice from the 2nd dropdown menu, and select the Staff Number of your choice. Click OK.
Repeat these steps for additional staves as desired. If changing the clef causes the music to be out of range for the instrument or voice, you can lower or raise any staff one or more octaves. Lowering or raising an additional octave only requires selecting By Interval and following the steps listed in the final paragraph for transposing for an instrument.
