A Few More Notes
You can change the overall feel of the improvisation by adding or changing a
few notes in particular swapping a G note for an F# note and adding more C#
notes and possibly a B note.
This makes the sound more "majory" - see my tutorial on major
style blues for an in depth look at this concept [The
Major Blues Style]
When improvising you can affect the sound you're creating as much by what you
choose to leave out as what you choose to put in - quite often "less is
more" so I wouldn't use all the notes outlined in the tab and diagram in
one piece.
Remember we're improvising within a framework here so you don't need to play
any of the ideas that I use - you can make up your own using the techniques
described.
This applies particularly to rhythms so try as many different ones as you can
and see what you can create.
Playing what you feel comfortable with rather than slavishly copying always
sounds better - try to make it your own!
