so i loaded this backing track

it says its in C


but when i click the black keys on my keyboard it sounds just fine to me.......

i must be either doing something wrong, or the backing track is in the wrong key

can you check please?

thanks

 

Yep. Its C alright. Being jazzy changes, the half step up/below could very well sound like it fits. I just tried some noodling in Eb minor pentatonic for example and it can work, heh. My jazz theory is shaky but the half step above or below is a thing. With the 7th chord tonalities, playing half step above/below is gonna be adding extension tones and so it works too. I mean, you can go playing a half step out then occasionally throw in a resolve note in key C, and voila'...jazz!
