Hello fellow fans of the harmonica! I am quite into harpboxing lately and created this little loop which i originally wanted to play over on another harp or add some vocals or something But i don't have the slightest idea as to which key the other Harp should be (this one is a B Harp) Anyways here is the clip I hope you guys can come up with a tipp or two! :)
Unless you are a really advanced player who can play in a lot of keys and positions you'll want something one step away on the Circle of Fifths. For B that means either a F# or an E harp. (My E is temporarily out of commision, but I picked up my F# with it and it sounded pretty good.) I'd probably go with the F# anyway.
I've got a couple tracks I've done this on. Usually I do F and C because I've got a double low F which gives me a nice low pitch for the chugging and a nice higher harp for the melody.
