If I am playing with people, and someone says "Let's play something in the key of G" (as in a jam session with no particular song to play), does that mean that I have the notes from the G Major scale to choose from?

I am not trying to be all that sarcastic, thats just the type of question that comes into my head all the time. I know what you mean but I can't even answer you or put it in a better way cause I just don't have the terms down enough to ask it.

Ed Fuqua said:Well yes and no. Just because a song is in a specific key doesn't mean all of the chords in that song are in that key. Plus there's some "common practice" stuff at work, when somebody calls a blues in G, the first chord is a G7 not a G major 7. But you don't call a blues in C and start on a G7, right?
Likewise when you're dealing with musicians who don't have a very complete background, they say "in G major" when the first chord they play is a Gmajor and the second chord is a Bb major. They are basically building a song on the chord shapes they know (nothing wrong with that, many fortunes have been made that way).

Xanadu said:Is there a reference somewhere that would show me the notes that a guitarist is playing when he/she plays a particular chord. I know that I could play the root note, but I have heard that the other notes that are fretted in a guitar chord will also work for me to play along.
Xanadu said:I knew it couldn't be that simple! I've got a lot to learn...here's to the search function!![]()
DaemonBass said:Ok so you want to jam in G but first you should know the chord progression, or given that you know the possible notes in that key, figure it out as you go along. For each key there is an order of note named chords. The types of chords they are is the same regardless of key, only the root notes will change. Here is a simple chart:
I (tonic or root of key) = Major Chord
ii = minor chord
iii = minor chord
IV = major chord
V = dominant chord (ie 7th chord)
iv = minor
iiv = minor 7th, flatted 5th (can also be plain minor, although not strictly diatonic)
and back to root
Xanadu said:When you talk about chords here, what exactly do you mean in terms of playing? How do I play a major or minor chord?
When you are talking about "ii = minor chord" when playing in G, do you mean an A minor chord? How would I play that?

Further, I've often found that when this type of jamming is done, it's done by the guitarist, who wants you to play some ostinato figure so that s/he can solo for many hours.
Something that comes with time and enough repititions of playing a certain scale or mode or arpeggio over and over and over and over again, is that you will begin to hear and understand that scale or mode at a deeper level.
