improvising and jamming in a key

Good Morning,

  You might want to check out the Theory section and the sticky at the top where Jerome has posted a nice tutorial on scales.  Once you have the chords down pat, you will want to be able to run the scales for each of the major and minor chords.  To start with, the Pentatonic scale is going to be the most useful in the beginning as it is used in most country and rock music.  A lot of the "shredders" out there toss in Phrygian and Lydian modes for additional flavor, but Pentatonic is a good place to start.

  You put this in the Acoustic section, so I'm going to assume that you are playing "un-plugged" mostly..... I'd be fiddling around with walking bass lines, hammers and pull-offs, a bit of bending and short fill licks to add character to a tune.  Kinda take bits of stuff that sounds good to you and fit it in where you feel it.  If it doesn't fit, just experiment. 

  Hop on to youtube and watch a little BB King and a few of the jazz greats to see and hear what they had going on.  Mr. King could say so much and make great music with just a few notes placed in the right places.

Take Care;
Doug

I second what jimhickeymusic says.  If you want to improvise in a key, you need to understand scales and how the intervals of notes relate to one another within a scale.  It's all patterns, so once you know the minor pentatonic scale for example, you know it in every key.  There are a ton of Youtube videos to help you learn scales and see how they relate to creating solos.
