yes, I used the sax solo sheet music from Curtis’ site to learn the solo and all Sax parts. Curtis’ Transcription for the solo in Alto is in Am and Dm for Tenor, meaning the song itself is in Cm like musicnotes.com shows it is because I always check with those folks like you mentioned, they’re very accurate. What I was getting at was Karaoke says the track they have for this song is in Fm and it’s not, their track in Cm–have a listen to the track and the actual song itself; they’re both in the same keys. So for them to say it’s in Fm was probably a typing error on their part; I’ve had that happen before with other tracks I’ve purchased from them. They have those features like you were saying to change the key a semi-tone/tone up or down. If you go down one semi-tone they say their track becomes Eb minor and typically it should–the problem is listen to it..that’s not Eb minor; that’s Bb minor we’re hearing–1 semi-tone below Cm.
