What does your fretboard say about you?

I like to play in the scale that suits my idea I'm working on at the time. I currently write a lot of stuff, and am learning Jazz soloing, so its a mixture of the aforementioned and choosing which scale will fit over a chord or series of chords. With the Jazz soloing its targeting chord tones though, so its not a scale I'm choosing per se, but basing my playing around a smaller selection of notes to fit in with the music, whilst playing around them for musical interest.

Tbh though, I've found when I create something from my head, I don't think about the scale, just the sound of the idea. However, I think that the idea I created was made possible because I know the scale well that the idea was based on, because I rarely create ideas that are not based on scales I don't already know.

A lot of study has been done on the emotional responses evoked by different scales in music. Here's one:

Sometimes, I'll try to play something specifically emotive, and turn to keys that aren't in my "normal" scales. For example, I don't usually play in the key of F#, but there's something about an F#m that I really dig. And, strictly speaking, to me an E, A, D sequence doesn't sound the same as G, C, F, even though they're the same pattern.

Thats interesting. When I create songs and riffs from my head, they are in a specific key, so it makes sense that specific keys have different emotional effects, otherwise whats the point in different keys in the first place?

Do you people notice a difference in using different scales to invoke different emotions?
