Sophia Actually, Sophia, there are shortcuts; maybe not for a particular tune, but as an approach to blues in general.
Short cut 1. Since many blues tunes use 7th chords, learn the Mixolydian modes.
Short cut 2. Learn those 7th chord inversions, like C E G Bb, E G Bb C, G Bb C E, because this will enable you to make those chord changes faster when you crank up the tempo.
Short cut 3. Recognize the "blue notes" of the chord scale. for a C7, chord, Eb (the flatted third) and Gb (the flatted fifth) used as passing tones will color your lines with that recognizable "blues sound".
Short cut 4. When playing an improvised line, make the chord scale note land on the beat. The is one of the key elements to playing be-bop. So, for a 4 beat measure of C7, you might play eighth notes: C D C B Bb E A G . Millions of possible combinations, even if it's a little ahead of you, doesn't hurt to think about it.
Short cut 5. Listen to old blues tunes that have piano, either supportive or featured, and try to pick out short little phrases that you can tuck away in your bag of tricks licks, ready to be pulled out at your next jam session.
