When you find yourself in a situation where the singer in your band can't hit that high note or your pianist refuses to play in C♯ major, the music transposition calculator may come in handy. This app is meant to make transposing music simpler. You can use it for transposing notes and chords.

Check out the text below if you want to learn how to transpose music or need a guide for using this key transposer.

What does "transpose" mean in music?

To transpose a note, chord, or whole piece of music means to change its key, i.e., move it by a specific interval up or down while maintaining its structure (rhythm, intervals between the notes, etc.).

In simple terms, transposition music definition is the lowering or raising of all sounds in a song.

How to use the music transposition calculator?

If the transposition music definition sounds too difficult to understand, use our tool which functions, e.g., as a musical instrument transposition chart.

Choose if you want to transpose by an interval/semitones (a major second down, 7 semitones up, etc.) or from one key to another (e.g., from F to G).

If you chose by semitones/interval:

  1. Select an interval from the list or enter the number of semitones. Once you set one variable, the other will show the equivalent result.

  2. Choose whether you want to transpose up or down (raise or lower the notes).

  3. Select how many notes you want to transpose.

  4. Select the names of all notes.

  5. Once you choose all notes, you'll see the transposed notes at the bottom of the music transposition calculator. Some of them will have two notation options. These are enharmonic equivalents - they relate to the same pitch but may be used in different musical contexts. For example, in the D major scale, you would use C♯, whereas, in A♭ major, you'd go for D♭.

If you transpose to key:

  1. Choose the key of your piece.

  2. Choose the key to which you want to transpose music.

  3. Select if the keys are major or minor (this music transposition calculator doesn't transpose between major and minor keys).

  4. Specify the number of notes.

  5. Select the names of the notes.

  6. The results will appear at the bottom.
