Open DTF

One of my earliest instruments was Disorderly Tumbling Forth, a keyboard instrument in which each key is attached to a framework containing about eight tubular chimes tuned to the same note. Repeatedly pressing a key in a slow tremolo creates a stream of chiming sound, so the instrument can be played melodically as a sustaining instrument. Several versions of Disorderly Tumbling Forth have followed, including non-keyboard versions. The one shown here is played by pressing the flexibly mounted steel frames that hold the chimes to shake them. Other DTFs appearing in this collection are a keyboard Disorderly Tumbling Forth and the Forest Vine DTF.

A video of this instrument can be found among the demonstrations in this youtube playlist.
