An interval is the distance between two notes. since there are twelve notes there are twelve intervals. Memorize the name, distance and sound of each interval.
C to C = unison same note in same octave (*see definition below)
(first interval) C to C# = minor second
(second interval) C to D = major second
(third interval) C to D# or Eb = minor third (Enharmonic - Same note written differently - this is done for the purpose of writing different keys see circle of fifths and fourths)
(fourth interval) C to E = major third
(fifth interval) C to F = perfect fourth
(sixth interval) C to F# or Gb = flat fifth or diminished fifth
(seventh interval) C to G = perfect fifth
(eighth interval) C to G# or Ab = minor sixth
(ninth interval) C to A = major sixth
(tenth interval) C to A# or Bb = minor seventh or sometimes called dominant seventh
(eleventh interval) C to B = major seventh
(twelfth interval) C to C = octave.
Octave same note higher or lower in tone by eight scale steps (like octopus) or twelve chromatic half steps (fret).
Example starting from C now transpose to all twelve notes:
C#(Db), D, D#(Eb), E, F, F#(Gb), G, G#(Ab), A, A#(Bb), B.
*Octave: For example, if one note has a
frequency of 600 Hz, the note an octave above it is at 1200 Hz, and the note an
octave below is at 300 Hz. The ratio of frequencies of two notes an octave
apart is therefore two to one.
