OPERATION

The results obtained depend more on the ability of the operator than on built-in limitations within the unit itself. A good “ear” for music is a must, of course, but, in addition, a moderate amount of skill is required, particularly in finger or hand dexterity and movement. The latter is learned only through practice. For a start, here are the basic “playing” techniques.

To sound an individual note, first move the “pitch” control hand to the proper position near the pitch antenna (as determined by practice) to sound the desired pitch. Next, move the “volume” control hand quickly to the proper position near the volume antenna to sound the note at the desired level, then away after the proper interval to sound an eighth, quarter, half or full note.

To sustain a note, hold both hands in position. The note volume may be increased slowly by moving the “volume control” hand slowly nearer the volume antenna, reduced by moving it slowly away.

To “slide” from one note to another, hold the “volume hand” fixed in position and move the “pitch hand” nearer (or away from) the pitch antenna.

To produce a vibrato effect, hold the “volume hand” fixed in position and shake–or tremble–the “pitch hand” at the desired rate.

To create a tremolo effect, hold the “pitch hand” fixed in position and vibrate– or tremble– the “volume control” hand.

Tremolo and vibrato effects can be produced by simultaneously rapidly moving both hands back and forth.

If you’ve used triangularly shaped control plates as the antennas plates in your instrument you’ll find that a given hand movement has less effect on operation near the narrow (pointed) end of the triangle than near its broad base.

Practice is important!
