Theory Lessons
Pitch as related to music.....
* Pitch is determined by the sound's frequency of vibration. It refers to the relative highness or lowness of a given tone: the greater the frequency, the higher sounding the pitch.
* The process of assigning note - names to pitches is called tuning.
* Interval is the difference in frequency between two pitches.
* The octave is the most basic interval. which indicates either a doubling or halving of the base frequency. In mathematical terms, every A can be expressed as:
2n × 440 Hz
