Musical Instruments for Playgrounds and Children's Museums

It's always a joy to sell to Children's museums and playgrounds. I love the fact that the instruments are explored and played to their full potential. I say with pride, that a few have even been worn out in the bigger children's museums. Below are some of the instruments I've made for either children's museum's or musical playgrounds. Most of them I tune pentatonicaly to concert pitch, but any tuning is possible. I can easily make instruments similar to those shown, but I also delight in custom instruments and new designs, so please share your ideas and wishes.

I'm happy to say that most of my steel instruments are made using old, recycled metals. They are likely to have blemishes of various sorts (ie.scratches, .pockmarks, etc.). Standard finish on the larger instruments is enamel paint. Powder coating is a pricier option that would give a more durable finish.
Please check out my new, dedicated Whale Drum page.

Heavy Duty and SHD Whale Drum

Very popular heavy duty versions of my Whale Drum made from old propane tanks.
The sound is deep and very resonant and "gongy".

These have become so popular, and have evolved so many options, that they now have their own Whale Drum page

24" HD Whale Drum (shown left, 8 notes, enamel finish)
For pricing and more options, see the Whale Drum page.

This recorded very softly, so you'll need to crank your computer volume way up and possibly wear headphones to do the sound justice. I'm working on a re-do

Dragon Gong and Monkey Gong

These stand about 5' high (but is hung) and can be played about anywhere. There are four to six tuned "tongues " on the front. There are eyes on the dragon, but they seem to have gotten lost in the background or the photo. These are not nearly as musical as The Whale Drum above, as the tone is very "tinny" sounding.


Aluminum Gong

A fairly simple, but resonant gong. The "dimpled" center helps clarify the tone. Made from 3/16 -1/4" aluminum sheet.

36" Gong (pictured) - $295

24" Gong - $145
Extra mallet- $8/ each

Hear Mama Stonaphone

Mongo Stonaphone  

This was made for the National Children's Museum of Jordan.
It's made from a variety of stones which were meant to be fairly rough and not tuned. The longest stone is about 42" long, the shortest about 24" long. They vary in thickness from 2"-6".
The sound is surprisingly resonant on some of the stone and more muted on others, but they all have clear pitch.
A similar instrument could be made with more uniform stone (as below), following a scale in concert pitch, and with a variety of possible bases(ie. stone, wood, metal,...).
(photo shows instrument on packing crate base)

 Tuned Mongo Stonaphone

This Lithophone has 3"x5" keys of a very dense, black metamorphic stone. It has a rougher look, bigger physical presence, and a more muted sound than the Mama Stonaphone. The base shown is of 4"x6" Cedar and measures about 36" wide x 44" long.
A Stonaphone similar to this would cost around $3200.
