To calculate ordered-pitch-interval between two notes...
- Count how many half-steps are between the two notes in question, and display that
as a number
- If the second note is higher than the first, put a + before the number to indicate
ascending
- If the second note is lower than the first, put a - before the number to indicate
descending
- Example A3 to B4 has an ordered-pitch-interval of +14
To calculate the unordered-pitch-interval between two notes...
- Count how many half-steps are between the two notes in question, and display that
as a number
- There is no + or - displayed for unordered-pitch-intervals
- This is most often used with pitches are played at the same time
