Strumming Volumes 1 and 2 are part of a series of lessons designed to give the guitar student all the fundamentals they need to become a solid rhythm guitar player. This lesson, Practice Partner Volume 1, includes strum-along exercises of the patterns explained in Strumming Volume 1. We recommend you consult the lesson A Chord Companion for information on fingering the common chords used on the guitar, as well as Fundamentals VII – Chords In A Major Key to understand the references to chords by number rather than name. Each of the five exercises presents one strumming pattern playing through a chord progression in five different keys. The keys used are those that are most common among acoustic guitar players- A, C, D, E, and G, with the addition of a couple in minor keys. They are graded in terms of tempo and number of chords used as well. The numbering of an exercise indicates a rhythmic patter followed by the key it is in. For example, exercise 4D would be the Ballad Pattern in the key of D, while 4E would be the same pattern in the key of E. A guide to the patterns used for each exercise follows.
