PLAYING EXERCISES AND TECHNIQUES

EXPRESSIVE VOLUME
There is a wide range of loudness that the thereminist can
employ to liven up their playing. Try playing with your volume
hand about three-quarters of the way up. From here, just a
casual raising of your hand or fingers makes the volume swell;
dipping your fingers or wrist slightly makes the volume drop.
This variation in volume adds articulation and depth to your
playing, while also highlighting specific notes or passages
of music.
Try attenuating the volume to emphasize the mood in your
playing, making some sections soft and others loud. If you find
that your volume sensitivity range is too small or too big for
you to easily control, you can adjust the
VOLUME RANGE knob
(page 20)
to specify the distance between the
near
volume
and the
far
volume to suit your needs.
Ideally, you should be able to go from full mute to maximum
loudness with just a flip of the wrist.
VIBRATO
Vibrato is an effect created by shaking your hand and
rhythmically “bending” notes back and forth, causing a
vibration of the pitch frequency.
This can make certain passages seem more mysterious or
interesting. A strong, fast vibrato will add tension or drama
to a passage, while a slow and delicate vibrato creates a subtle
movement that can soften or sweeten a passage. To perform
vibrato, simply give your pitch hand a slight wiggle. The trick
is learning to sync the back-and-forth motions in a way that is
musically appropriate to what you are playing.
Keep your movements small and gentle. You are bending
the note up and down just slightly. Vibrato that is too wide,
covering several steps, is a trill and generally doesn’t sound
as pleasant. There is no “correct” way to perform vibrato, but
generally you want to find a technique that is both precise
and physically comfortable to sustain.
Using only your wrist to provide the necessary back-and-forth
motion can become painful even after just a few minutes.
Instead, try leaving your wrist relaxed and flexible, using mainly
forearm movements to shake your hand.
