Hard to say, I feel it helped a little, as in, when I&#x27;m playing with my teacher (without MeloCraft), I more often get the feeling « oh, that doesn&#x27;t quite sound right, I should move my fingers a little bit ». But that&#x27;s N=1 and I didn&#x27;t do any meaningful before&#x2F;after tests.<p>That said, even if the tool doesn&#x27;t help for the musical earing directly, it can still help to correct the position of your fingers, and that&#x27;s very important for muscle memory. So instead of training for hours on the wrong finger position because I don&#x27;t have a musical ear, I can correct myself and properly train my muscle memory correctly.<p>Well, you&#x27;re very lucky to have a relative pitch, I think you can still train for it as an adult, but it may require more time and still might not be possible for everyone. Don&#x27;t take my word for it thought, I don&#x27;t recall any solid research on the subject.
