FAQ
Questions Interval Calculator owners ask.
- 01
How do I find the distance between two notes?
Use the calculate_semitone_distance capability by providing the starting note and the ending note (e.g., 'C4' and 'E4'). It will return the total number of semitones between them.
- 02
Can I check if an interval is consonant or dissonant?
Yes, use the identify_interval_properties capability. It will tell you if the interval is classified as 'Consonant' or 'Dissonant', along with its name and inversion.
- 03
How do I calculate the frequency of a specific note?
Use the calculate_note_frequency capability. You need to provide the note name, the octave, and choose between '440Hz' or '432Hz' as your tuning standard.
