Guidelines for searching by interval:

Intervals consist of three components which must occur in the following order for each interval:

interval direction
- The plus sign (+) indicates a rising interval.
- The minus sign (-) indicates a falling interval.
interval quality
d or D = diminished
m = minor
M = Major
A or a = Augmented
P or p = Perfect

diatonic interval size

Additional guidelines for searching by interval:

If a component is missing from the interval, then any of the possible combinations will be searched for. Examples:

`m2`	will expand to either `+m2` or `-m2` because the direction of the interval was not specified.
`-3`	will expand to `-m3`, `-M3`, `-A3`, or `-d3` because the quality of the interval was not specified.
`+P`	will expand to `+P4`, `+P5`, `+P8`, etc. because the size of the interval was not specified.
`+`	will match any interval which is rising.
`M`	will match any major interval which is either rising or falling.
`4`	will match any interval with a diatonic size of 4 which is either rising or falling.

Advanced interval searching:

.

To search for an unknown or arbitrary interval, use the dot to represent any one interval. Example:

(+M2 . -m3) will match to (+M2 -M2 -m3)
(+M2 +P4 -m3)
(+M2 -P5 -m3)
(+M2 P1 -m3)
etc.

?

To indicate an optional interval, append a question mark. Example:

(+M3 +m3? -m3) will match to (+M3 +m3 -m3)
(+M3 -m3)
etc.

*

To indicate any number of optional intervals, insert an asterisk. Example:

(+M2 * -m3) will match to (+M2 -M2 P1 +M6 -m3)
(+M2 +P5 -m3)
(+M2 -P4 +m6 -m2 -m2 -m3)
(+M2 +m7 -P8 +M2 -m3)
etc.

^

A caret appended to an interval indicates an optional inversion of the interval. The inverted interval is in the opposite direction. Examples:

#

To search for an interval or its inversion in the same direction, append the number symbol. Examples:
