Guitar Chords, Progressions and Formulas
The table below, illustrates the notes and chords in the key of C major.
To use the illustration above, you must understand the numbering system. Look above and notice the number under the C in the first box. The number (1) under the C, is also the roman numeral (I). Each note of the major key, has been given a roman numeral to represent it.
The C =1 or I, the D = 2 or ii, the E =3 or iii, the F = 4 or IV, the G = 5 or V, the A = 6 or vi and the B = 7 or vii.
You can use the lower illustration to play a number of different progressions. I would like to explain of of the most popular progressions that uses the I, IV, V chords. In the key of C major, the chords would be C, F and G. Look below at the 1, 4 and 5 chords. The 1, 4 and 5 guitar chords in the key of C major are the C, F and G.
Roman numerals are usually illustrated to show each note of a particular major key. It would be a good idea to become familiar with this technique. The small letters, (ii, iii, vi) represent the minor chords. Look below at the Dm, Em and Am guitar chords. Roman numerals I, IV, V represent the major guitar chords.
