Changing the key of a piece of music is called transposing the music. Transposing music is not the most difficult element of music theory, but it does require a mastery of the various key signatures and modes to be done correctly. Beginning musicians needs a simple tool that could transpose backing track to put it in the right key for vocalists.
Where to start? Consider the simplest option - you know the current key and need to change it to another key. First, we need to determine the interval between the keys in halftones. If we play each note on a piano one by one from left to right, we get 12 tones which make up the chromatic scale:
C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B
Now just count the intervals and set them in the settings of the software. Of course you will not be able to change key for whole octave without audible distortion, but it is real enough to correct vocal within two semitones.
AudioRetoucher makes transposing music easy. It allows you to change the key of any MP3 file without changing the tempo.
