Slit Drums

 Slit drum, tongue drum, Teponaztli. Wooden drums usually made from hollowed logs are common among many cultures around the world and have various names. The 'tongues' were usually cut in the shape of an 'H' on the top forming 2 different lengths which in turn produced 2 different pitches.

About 30 yrs ago I made 2 for myself. The sides and bottom were plywood with a top (for the beating surface) of a maple board. 


 The larger one (not pictured) had a great sound but the smaller one (above) have the tongues too short for a good resonant sound. Unfortunately the larger one was loaned out to a local high school and was never returned.

Obviously my Teponatzli is not as visually striking as the one made by the ancient Aztecs, but the sound is similar. It was another fun project.

The Amadinda

  The Amadinda is an African xylophone originally made from slabs of wood or even large sticks, with or without gourds for resonators. There was no reason for this project other than to see if I could make a simple mallet instrument. The box was made from plywood (which also acted as the resonators) and the bars were made from maple.  Since this was to be a true xylophone, the bars were all of equal width. Tuning was done by cutting the bars to different lengths and removing material from the bottom. Using a router I created a sort of 'stepped pyramid' instead of the traditional arc cut found on marimba or xylophone bars.  Cutting the underside is not only for tuning but it focuses the pitch and creates the characteristic overtones of the instrument. Since I wanted to play this with other 'Western' instruments, I chose to use a pentatonic scale of 2 2/5 octaves (C#,D#,F#,G#,A#,C#,D#,F#,G#,A#,C#,D#). Two people sit on either side of the instrument and strike the ends of
