Hi, I am currently in the process of writing a new song. But this time instead of the keyboard as my starting point for the song I am using my trumpet. Here is the problem. I cannot, for the life of me find out what scale I am in.

On trumpet (it is a Bb Instruments so any note I say, decrease its note value by 2 half steps)

So I am writing song in 6/8 with a bunch of fast note changes (though they are few)

It starts out on C# drops down to A, then back up to C# again. Then drops down to Bb and up to D. Then I go from that D to an E then back down to a C (natural). Then repeat.

When I do screw around with scales for it, it makes it sound Middle eastern or Egyptian, which I do not want.

Bah, I don't know why I cant figure this out. Been struggling with this for the whole day

Anyway here is a properly transposed (from Bb to C) Midi file with the riff it self I am working with.

Thank you.
