say my rhythym guitarist is playing a rhytym based in E minor, and i want to use a lead that is a diminished arpeggio. the diminished arpeggio has notes that arent in E minor. How is this in key? would the rhythym have to be based off of the diminished scale as well?

i noticed that e m6/9 also contains notes that arent in the e minor scale.

can someone give me a quick run down of using arpeggios?

Notes outside of the E minor scale will add tension to the lick and so long as you resolve on a note that is in the key of E you'll be fine. Having said that, E diminished is in the key of E so should sound OK when played over a progression in the key of E. The best rule to follow is to play what sounds good. Experiment and see what sounds good to your ears.

what defines something as "being in the key of E". i never got that. i suck so much at theory.

if you use notes only found within a certain scale it will be in key.

for example if you use te scale of e minor, and you only use the notes within that scale it is in key.

Thanks for the help btw

If you play any E scale, it will be in key when played over a progression in the key of E - the different scales just add different flavours over the progression. Of course, this is only a rough guide and certain scales will fit better over certain progressions but like I said, whatever sounds good to your ear.

or it just starts and ends with E....geez....

Scales exploit our preconcieved notions of what is satisfying.

Playing notes outside the diatonic scale creat edissonce, which at slow speeds, generally sounds like noise. The trick is to play through outside notes fast enough to create a context of the scale as a whole. In this case, the outside notes are used to imply other "darker" scales, such as the phrygian mode, or of course for the diminshed, the locrian.

^^^^The best ive heard it put in a long while.^^^^

Yes.



You can play notes outside the scale at any speed - Robert vigna of Immolation is a master of this.
