I will break things down to 3 basic elements in your soloing to think about as you record or perform some lead guitar.
Let a simple 3 or 4 note melody or motif be a good starting point
to your solo. It can be something inspired by the song's melody or just
a line that adds to the existing material in the parts of the song.
CHORD NOTES OR TRIADS
Try to follow some of the outlines of the chord tones
throughout your soloing. Sometimes it's just a targeting the
first or last chord of the progression and highlighting those notes
to create resolution and musical poetry.
CLASSIC PENTATONIC SCALE RUNS
One can really tie things together with classic blues
and pentatonic runs. They seem to fit in almost any occasion
and give soling that classic element that everyone knows
and loves about the guitar.
Put these three elements together next time you get to solo, and you will be pleased at the outcome. You'll have to work a bit to become quick at hearing and making melodies, know the locations of some basic triad (chords) shapes, and memorise some classic bluesy runs to begin playing like a pro.
UNTIL NEXT TIME....
