My students often inspire new projects.
Below are a few things that I've built as a result of student inquiry or my own curiosity.
A lapharp is a simple instrument but has a good range of capabilities. It is played with a guitar pick or by finger plucking. I built this instrument for my nephew.
A set of pipes cut to a chromatic octave. The lengths were found using geometry.
A Pair of Monochords
These instruments were built to demonstrate the ratios needed to create different pitches from one string.
A study of the math behind the construction of organ pipes led to the construction of a set of wind chimes.
Hearing intervals is important but seeing them is pretty neat too! Simply adjust the weights and the upright poles rock in different frequencies. The pen then draws the ratio.
