This transcription,is the single 12-string guitar solo of the
 song "In My Life", from the album "Inner Worlds " by John McLaughlin 
and the Mahavishnu Orchestra. 
 (The opening dual-12-string cadenzi are something else!)
 Bar 8 has 29-some notes over 3 beats(,,,) breathe deep...

 The solo is based on a D Ma7_GMa7_D Ma7_GMa7 sequence over
                        4/4___4/4__4/4____3/4 cycle 
 It is a 16 bar solo based on the changes printed here,

  _____4/4______|3/4| 
 These are rudimentary "one-finger" chords.GMa7 may be GMa7/A *

Note the use of Dmajor R_2_3_5_6_Oct_9...pentatonic pattern,first soloing over both
chords adding to the GMajor bars a 2_3_5_6_7_9 scalar flavour (G tonic-less,at that).
Then McLaughlin adds the scalar 7th C#, scale tone on G, Lydian #11th.
