"Music Theory Intervals"
Distance between Two Notes
Let's explore the element of
intervals. The distance between two notes is the
determination of an interval.
What is special about intervals is that
they are easily defined and shown by the number of
half steps from a starting note.
are not going to attempt to explain the pitch differences but only
explain the interval idea. The names will give clues and explore them
in wikipedia will give you an in depth understanding. We are most
concerned at this stage with the application or math of the music
Interval Names Overview
The names of an intervals are stated in such terms
as a second, third, fourth, fifth, and continue up to fifteenths.
What is more difficult is that for a name it can
be modified for different position with some of these
modifiers M=major, m
or (-) = minor, #=sharp, b=flat, octave=8va which change the position.
We might say minor 6th. which is a half step down from a sixth.
Now that can start to be confusing and we are not
about to let that happen.
Music Theory Intervals in One Octave:
We have defined the 7 base note names, A - B - C - D - E - F -
G. By using the keyboard below starting on the C note we
can examine the basic interval from 2nd to 8th (octave) by
using just the white keys. (This is the key of C, the C scale, and has
no sharp or flats, the black keys)
