Although electric six-string guitars are typically tuned to the same pitches as acoustic six-string guitars, the strings on an electric guitar are thinner and not as tightly wound as those on an acoustic. Without electronic amplification, these thin, loose strings barely make a sound. However, thinner, looser strings are much easier to play, notes are much easier to bend, and electronics allow for all sorts of fun effects. The guitar course includes music reading, ear-training, technique, and music theory, which provides an understanding of chords and improvisation.
