Adding a B note
Example 1 - I use the note B as a bounce off note when the chord sequence is on the A or D part.
Example 2 - I use the B note as a quick passing note by sliding down from a C.
Example 3 - I use the B note to bend up to C# and then play the unbent note as well - still as a bounce off note as in example 1
Example 4 - the B becomes a strong note when the chord sequence hits an E - this means that you can hang around on this note rather than using it as a bounce off or passing note.
