Music Theory Basics
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 valuable tool for musicians and Music enthusiasts. It helps users calculate musical intervals, frequency ratios, and note relationships. By simply selecting notes or entering frequencies, you can find out the distance between notes, transpose melodies, or convert frequencies to their corresponding notes. This calculator makes music theory easier and more accessible for everyone.
Calculate Note Relationships with Ease
One of the primary functions of the Semitone Calculator is to calculate note relationships. You can input two notes, and the calculator will determine the semitone distance between them. This is perfect for musicians looking to understand how different notes relate. With this feature, you can explore various musical intervals, such as major and minor seconds or perfect fifths.
Transposing Made Simple
Transposing music can be tricky, but the Semitone Calculator simplifies this process. You can enter a series of notes and specify how many semitones to move up or down. This feature is particularly useful for changing the key of a song. You can easily adapt your music to fit different vocal ranges or instruments.
Frequency to Note Conversions
Another fantastic feature of the Semitone Calculator is its ability to convert frequencies to musical notes. By inputting a frequency in Hertz (Hz), you can find the closest note and its corresponding MIDI number. This is a handy tool for tuning instruments or working with electronic music, where precise frequency matching is essential.
