Frequently asked questions
Does the speed change too?
No. The pitch changes and the duration stays the same, so you can change a song's key to sing karaoke or play along on an instrument.
How many semitones should I use?
Each semitone is one fret on a guitar. +12 is one octave up (very high voice) and −12 one octave down (very deep voice). To change a song's key, 1 to 3 semitones is usually enough.
