So vibrating objects – such as musical instruments – cause sound vibrations that our ears can easily interpret. The measurement unit for vibration frequency is known as Hertz or Hz. Sound is itself another type of vibration, caused as air molecules vibrate and collide, and pass on energy. What are musical frequencies and why frequencies are important for musicians?įrequency is a measure of vibration or oscillation, related to how quickly an object or a signal moves backwards and forwards between two positions. We also take a look at the concepts of the ‘equal temperament’ scale and see how audio frequencies combine in songs and performances to give our ears a rich and organised sound experience that we refer to as ‘music’.

We cover all aspects of musical frequencies relating to notes on the piano keyboard and the intervals between notes. In this article we unpick the key concepts relating to musical frequencies, and link these to the tuning of musical instruments and the creation of music, focusing particularly on drums and drumheads too.
