- Music theory helps you understand the structure of music, so you learn faster, play together better and become more creative.<\/li>\n
- The basics consist of notes, intervals, scales, chords and rhythm.<\/li>\n
- Chords come from scales: a triad is a root, third and fifth.<\/li>\n
- Rhythm and time signatures give you a good sense of timing and groove.<\/li>\n
- Reading sheet music and tabs gives you access to more music, and theory makes improvising and composing easier.<\/li>\n<\/ul>\n
The basics: notes, pitch and the guitar neck<\/h2>\n

<\/p>\nNotes are the building blocks of music. Every note has a pitch and a duration. The musical alphabet has seven natural notes: A, B, C, D, E, F and G. Between B and C and between E and F there is a half step, between the other natural notes a whole step.<\/p>\n
The open strings of a guitar in standard tuning are, from low to high, E, A, D, G, B and E. Each fret raises a note by a half step, and at the twelfth fret you hear the same note as the open string, an octave higher. Learn the notes on the low E and A strings first. That is where the roots of most barre and power chords are, so you use that knowledge right away.<\/p>\n
Intervals and the major scale<\/h2>\n
An interval is the distance between two notes. The smallest step is a half step (one fret), two frets is a whole step. A major scale always follows the same pattern: whole, whole, half, whole, whole, whole, half step. Starting from C, that gives C-D-E-F-G-A-B-C, with no sharps or flats. Starting from G you need an F# to make the pattern work: G-A-B-C-D-E-F#-G.<\/p>\n
Scales are series of notes that together evoke a certain mood. They form the basis for melodies and solos, and, as you will see below, for chords too.<\/p>\n
How chords are built<\/h2>\n
Chords are not loose finger positions, but combinations of notes that sound together. A triad consists of a root, a third and a fifth. In a major chord the third lies four half steps above the root: C major consists of C, E and G. In a minor chord it is three half steps: A minor consists of A, C and E. That difference of one half step largely determines whether a chord sounds bright or melancholy.<\/p>\n
If you build such a triad on every degree of the major scale, you get the chords of that key. In C major those are C, Dm, Em, F, G, Am and Bdim. You can read how to build progressions with them in understanding chord progressions<\/a>. If you understand the theory behind chords, you can also make variations of your own that fit your style.<\/p>\n\n
