What distinguishes the Piedmont blues sound from, say, Delta blues or Texas blues (generally speaking)?
Generally speaking, the Piedmont blues sound incorporated ragtime piano rhythms and chord changes in guitar playing. The left hand piano rhythm is reproduced with the thumb and the right hand piano melody with the forefingers. This is often called “finger-picking style.” This type of playing has been described by some critics as being more “melodic” than other blues, with an alternating thumb bass pattern supporting the melody on treble strings.
