Pasco - Model WA-7428 -Sonometer for Two-String Guitar Device
A sonometer is a two-string guitar device that uses hanging weights to create tension in the strings. The two strings have different densities. The student can vary the lengths of the strings using the included bridges and a pick (included) or finger to pluck the strings. Sonometers are used to study standing waves in strings, wave speed, and musical instruments.
With this two-string guitar, students can hear the resonance modes of the strings.

The Sonometer is an apparatus used for exploring the wave properties of vibrating strings. It includes two mounts to install strings of different linear densities onto a sounding board. String length is varied by changing the position of a sliding bridge under the string. String tension is varied by hanging masses from the lever attached to the end of the string. To vibrate the strings, pluck them with a pick or use resonance by vibrating a tuning fork. Use a sound sensor with SPARKvue or PASCO Capstone to measure the frequency of vibration.
