Chopbuilder Part II:Interval Connections
An INTERVAL is the distance between two tones, or notes.
They can be played simultaneously or individually.
On the guitar, it is easy to count and visualize the distance between two tones, and we measure in frets. In our system of Western music, these distances are given universal names so that they are applicable to all instruments.
Here are the names to become familiar with, along with the equivalent in frets on one string:
KEY OF E:
UNISON : E and E (same pitch) no distance
MINOR 2ND: E to F (1 fret)
MAJOR 2ND: E to F#(2 frets)
MINOR 3RD: E to G (3 frets)
MAJOR 3RD: E to G#(4 frets)
PERFECT 4TH: E to A(5 frets)
TRITONE (#4/b5): E to Bb(6 frets)
PERFECT 5TH: E to B(7 frets)
MINOR 6TH: E to C(8 frets)
MAJOR 6TH: E to C#(9 frets)
MINOR 7TH: E to D(10 frets)
MAJOR 7TH: E to D#(11 frets)
OCTAVE: E to E(12 frets)
MINOR, MAJOR, AND PERFECT INTERVALS.
Minor is the smaller of the two in each of the cases (2nds, 3rds, 6ths). 4th and 5th are perfect. Tritone is the equal division of the twelve tones available.
