Transpose Music to another Key

Transposition is the process of moving a collection of notes (pitches or pitch classes) up or down in pitch by a constant interval. Music in a major key can be transposed to any other major key; music in a minor key can be transposed to any other minor key. Music Speed Changer makes transposing music easy. (For fractional frequency shifting with Music Speed Changer see pitch shift info here)

Transposition Setup

To make transposing music easier, snap the pitch to semitones and enable Key to see the piece's original key and the key you want to transpose (pitch shift) to. Below are the adjustments to make to the editor settings to optimize Music Speed Changer for transposing music.

Adjusting the Editor Settings

To see the keys, set up the editor window to show the Key section. There are two ways to do this, either use the preset Key and BPM or add Key to the custom setup.

Open the editor by tapping the up arrow or swiping up the mini player

Opening the Key & BPM Editor Component

Open the Editor Layout Menu by tapping the slider/gear icon at the top of the editor. Here you can select one of the editor presets or you can customize the editor


Select Key and BPM



Or if you want to add Key to your custom setup, Music Speed Changer allows you to that.

Adding Key to Custom Editor Components

Open the Editor Layout Menu by tapping the slider/gear icon at the top of the editor


Select Custom components


Tap on Musical key to turn it on


This will add a Key section to your editor

Snap the Pitch slider to Semitones

To make the key change in semitone increments, we need to snap the pitch to semitones.

In the Editor Layout Menu


Check Snap pitch slider

Working with the Pitch slider and Key to Transpose a Track

Now that the app is set up for transposition, transposing becomes easy.

Slide the slider to shift the entire track by whole semi-tones. As the pitch shifts, the key changes


Happy transposing!
