i looked in the help thread and there was nothing about this so dont direct me there.

i need help being able to tell weather or not im in a major or minor key.
i really have no clue how to tell. could somone please help me, thanx
Well... basically if the song sounds sad or has a minor sound then you're in the minor key, also look for the chords in the song. If you have mostly minor chords instead of its relative major equivalents then it's pretty safe to say it's in minor key.
but say i want to do some improv in G minor.
how do i get the key to be minor?
total noob question sorry guys.
Use a G minor scale. The most common minor scales are natural minor (aeolian mode) and harmonic minor, and the two are often mixed in a song.
