Watch the Using Trills online guitar lesson by Dave Celentano from Classical Concepts for Rock Guitar

A trill is the rapid repeating of two notes back and forth. Although the trills in this concept are all half-steps (one fret apart) and use the index and middle finger combination, other trill types should also be explored including a whole step trill (two frets apart) using index and ring fingers and a minor 3rd trill (three frets apart) using index and pinkie fingers. Crossing from string to string should be performed swiftly and clean, with no interruptions and with as little string noise as possible.
