Though I've taken vocal lessons for about a year I'm an inexperienced vocalist (Approx. Range ~D3 - ~D5).
I'm currently using karaoke versions of songs as backing tracks and sing on top of them. For those that are not in a key that I'm comfortable with I change their pitch with audacity (e.g Don't Stop Me Now - Queen, F Major -> D Major).
The result is disturbing as the melody gets distorted and the general outcome feels like my voice does not match the track (or vice versa) while being on key.
What course of action should I take in order to tailor the song to my voice?
