What are Semitones?
A semitone (or half step) is the smallest musical interval commonly used in Western tonal music. It's the distance between two adjacent notes on a piano keyboard. In equal temperament, a semitone represents a frequency ratio of approximately 1.0595:1 (the 12th root of 2).
Common Musical Intervals
| Semitones | Interval Name | Ratio (Just Intonation) | Example |
|---|---|---|---|
| 0 | Perfect Unison | 1:1 | C to C |
| 1 | Minor Second | 16:15 | C to D♭ |
| 2 | Major Second | 9:8 | C to D |
| 3 | Minor Third | 6:5 | C to E♭ |
| 4 | Major Third | 5:4 | C to E |
| 5 | Perfect Fourth | 4:3 | C to F |
| 7 | Perfect Fifth | 3:2 | C to G |
| 12 | Perfect Octave | 2:1 | C to C' |
Note Frequencies
In standard tuning, A4 (the A above middle C) is set to 440 Hz. Each semitone up or down changes the frequency by a factor of the 12th root of 2 (approximately 1.0595). The formula for calculating the frequency (f) of a note is:
Where n is the MIDI note number (A4 = 69) and A4 is the reference frequency (typically 440 Hz).
Understanding the Semitone Calculator
The Semitone Calculator is a handy tool for musicians and Music lovers. It helps you understand how notes relate to each Other, making it easier to compose, arrange, or simply play your favourite tunes. Whether you want to calculate the distance between notes or transpose melodies, this calculator simplifies the process.
Calculate Note Relationships
With the Semitone Calculator, you can easily calculate the relationship between two notes. Just select your first and second notes along with their octaves. The calculator takes care of the rest, telling you how many semitones apart they are. This is especially helpful when wanting to know the interval between notes, which can improve your musical understanding.
