Quarter Tone Transposition App

This tool can be useful for composers who are new to writing quarter tone music. However, it is recommended that composers who work with this kind of music learn to transpose independently, as it will expedite the composing process and give the composer a more firm grasp and understanding of quarter tonality.

The input notes will appear in the top row, which is initially empty. To add notes, click on the desired notes on the section below. To remove notes, click on the desired notes in the top row. To change the from and to keys, click the button, then select the desired keys. The output will automatically appear on the bottom row of the app.
