What Keys?

[GlennPagano]

I made a nice bass riff with these notes. What keys would they be in?

B,C,D,E,A,Eb

That's tricky, I don't know that you can say "It's in the key of X"

By the time you get an Eb or D#, some other notes which you have used as naturals are included in that key's sharps/flats (See: http://en.wikipedia.org/wiki/File:Ci...s_deluxe_4.svg)

So it's up to you to pick a key and mark the accidentals in your bass line. You could be best off in the key of C/a and just flat a few E's.

I find this to be a pretty good tool for that sort of stuff http://jguitar.com/harmonizer/chord2...dlist=E&chord=

Looks like you've got the key of Glenn. If you like the sound that's all that counts.
C Melodic minor comes close C, D, Eb, F, G, A, B, C
Hunting for a Key - see if all of your notes fit into a specific scale. Helps to have a handy dandy scale chart.

Course if you pick a key and then noodle you always know what key you are using.

it's the Eb that makes identifying a key difficult.

There is no key that explicitly contains E, Eb, and D by name.
No key will explicitly have 2 different sharp or flat versions of a particular note:
Each Note letter is only going to be used once.

With E taken, normally that Eb would be called D# ,
but since D is already spoken for, it indicates that the Eb is likely to be an accidental (a note outside of the key sig)

If that Eb is being used as passing note from D to E, It could be an A minor blues riff.

at the end of the day it all depends on what notes you are emphasizing

B melodic-mixolydian?

theres always a key, even if you are using notes outside of key, its not a matter of matching up the notes you play with a graph and saying "thats th ekey" its about what the "color" of the melody/song indicates, i've layed in A minor where C# is a part of the melody but its still in A minor
