Transposing the audio backing track

If you have chosen the audio file (.mp3 or .wav) as a backing track for playing along, but it's music key does not match the harmonica's key you have, it is possible to align keys by transposing the sounds (changing the pitch) in the file using the software program (e.g. Amazing Slow Downer - ASD). Changing the pitch up or down by one or few tones may align the music to the key of your harmonica. The transposing may help not always, but in many cases you will succeed, if your chosen audio file is suitable.

Example:

Let's say we have the diatonic harmonica in key of C which is suitable for playing blues in the key of G in the second position and "Manic Day" mp3 backing track clip in key of A. To play along this clip on key of C harmonica we need to transpose it to the key of G. We can make it with ASD, lowering the pitch by 2 semitones, so that resulting key of G backing track will sound in line on the key of C harmonica.

If you own the key of C diatonic harmonica, give a try (click links above) to play along your self with both sample tracks to feel the difference.

Using the method of audio file transposition you will enjoy many sound tracks of your favorite groups or artists which you would love to learn playing on your current harmonica while you have not decided yet to buy a whole set of harmonicas in different keys to be able to play all the music you want.
