Make musical notes by plucking a stringed instrument. Explore how a vibrating string creates pressure waves through the air. Look at graphs showing sounds as a waveform. Explore the relationships between string length, musical pitch and wave frequency. Compare musical notes with soundwave patterns and predict one from the other. Match sounds or tunes correctly to score points. Compose your own tune or copy a simple tune. This learning object is a combination of four objects in the same series.
Objective
Students adjust the length of a string to change the frequency of vibrations and produce musical notes with a range of pitches.
Students compare musical notes with soundwave patterns and predict one from the other.
Students identify and produce sounds of a given pitch and assemble them into known tunes or new compositions.
