Toulouse Street, the title song from The Doobie Brothers second album, released in 1972, is a haunting little acoustic guitar fingerpicking piece written by Patrick Simmons.
It was done as a guitar duet with each in slightly altered tunings. This lesson looks at the opening guitar part, which was done with a capo at the third fret.
It is really just straightforward alternate bass picking with the fingers emphasizing melody notes between the beats.
It is quite fast and includes a rapid run of pull-offs as well as an unusual arch-barre, where the index finger plays two notes on adjacent frets.
