Cello Drones is required for all my students at the Berklee College of Music in Boston. The beauty of the sound creates a peaceful environment which makes practicing or improvising a true delight. I am seeing steady progress in intonation as my students and I work with the drones. Some days I press play and practice with the entire CD, it is both pleasurable and useful.

~ Eugene Friesen

...truly well done, fun and highly useful to sing or play with, starkly beautiful in their own right, you've made a core musical experience more available to more folks.

~ Allaudin Mathieu - composer and author of The Listening Book and The Harmonic Experience

Even guitarists like cello drones:

I'm really digging the drones! What a cool concept. They're helping me overcome “fret-induced tonal atrophy.” I've been improvising over the drones and I'm feeling much more conscious of each note and the intervals with the tonic and 5th.

~ Jonah Steinbuck, Palo Alto CA

Playing with Cello Drones is an effective and enjoyable way to develop your ear and improve your intonation. A drone is a sustained tone, and playing or singing with a drone allows you to hear and adjust in relation to an ongoing reference pitch. Tuning to a drone develops awareness of frequency relationships which can carry over into listening and tuning in all playing situations. It adds a harmonic element which enhances the musicality of scale and passage work. As in many musical cultures, playing with a drone also provides a tonal atmosphere and harmonic base for improvisation.

Take a two-minute spin around the circle of fifths and hear the sound of the cello drones:



The Cello Drones CD contains drones on all 12 chromatic pitches for tuning and improvisation in major, minor, modal, and scales of your own creation. Each track is approximately 6 minutes in length and consists of 5 sustained tones: 3 octaves of the tonic (the fundamental scale tone) and 2 octaves of the 5th. Software techniques have been used to ensure pitch accuracy. A = 440 Hz.
