Simple R5 Chords
The following 2 tone chords are incredibly common. They are R5 chords, where R stands for root. The root is the tone that names the chord; the base tone for the chord. The 5 is the tone that is 5 tones away [7 half steps] from the root. A5 =AE = 12345 = ABCDE.
For these chords, we are ‘strumming’ 2 adjacent strings as a block. We will cover strumming in a subsequent lesson. For now, hit 2 strings as a block [whether hitting 2 strings as a block constitutes strumming is a semantic question – I call consistent, smaller range ‘strumming’, pick-strumming – boundary between picking and strumming].
These chords can be called power chords. This term can have different meanings to different players at different times. For now, memorize these chords, & know that they can be called power chords. These chords are also neutral in that they can be used for Major or minor type chords, since they are neither.
For our mapping process, this is R5 chords in a fixed position. We are in the key of A. All of the shapes are in one place (fixed – no shifting).
