Guitar as a Sonometer

PIRA 3D20.10

Description:

Three main sonometer topics can be easily heard in a guitar. 1)Since the string tensions are all about the same on a guitar, the effect of wire size can easily be heard. 2)Making the string shorter by placing a finger just above a fret gives different pitches (notes). 3)Adjusting the tension of the string allows for exact tuning of the instrument.
