The Ventures have to be the quintessential surf band. The template for how they arranged surf music has become the standard for creating the classic surf sound. Nokie Edwards' clean jazzmaster tone and Mel Taylor's aggressive drumming generated a powerful joyful sound.
The majority of early Ventures' tunes are based on twist beat. The rolls of the guitars are pretty simple. One guitarist plays the melody and one plays rhythm. The melodies are usually clear, simple, and tend to favor the low register or open position and use techniques like tremolo picking, double stops and vibrato bar bends. The rhythm guitar comps using open chords, simple barre chords, rakes and tremolo picking.
There's isn't a lot of improvisation in this style of surf music; these are set arrangements. Of course, this is a generalization and there will always be exceptions to the rule.
