Drone Tone Tool is an app created by professional musicians and music educators providing high quality reference pitches with the rich overtones of real cellos. We encourage musicians of all abilities to experience the benefits of reference tone practice! Why real cello drones? There are many electronic tone generators, and while they are better than nothing, they lack complexity of overtones and can be painful to listen to. Our cello drones are pleasing to the ear, rich in overtones and contain layered octaves to facilitate practice in all registers. Purpose and benefit of reference/drone tones: A reference (or drone) tone provides a center of harmonic stability. Our ears are able to discern the way that multiple pitches interact while strengthening our internal sense of pitch. By playing with a movable pitch (instrument or voice) relative to a fixed pitch (drone tone) we can start to perceive truly consonant perfect intervals, and 'shades' or 'colors' within Major/Minor intervals. This heightened awareness of relative pitch leads to artistry through intonation. ## Key features - High-quality reference pitches - Rich cello overtones - Develop internal pitch sense - Improve intonation - Harmonic stability - Practice in all registers ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/dronetonetool/id1191100591/reviews.md ### 5/5 — Very helpful for choir practice *2019-09-16, version 1.2.5* Very helpful with finding my note foe choir practice. ### 5/5 — Cello *2019-08-18, version 1.2.5* As a cello player, this is an excellent tool. It also comes with a metronome which very handy. ### 5/5 — Practical and useful *2018-11-25, version 1.2.4* I Play the cello and this app has helped me play through hours of scales. I would highly recommend either the online or app version!! ### 3/5 — Not much for a paid app *2018-10-04, version 1.2.4* Just droning and metronome. Can only change the metronomes tempo to presets. Cant adjust the volume of the metronome/drone so they mesh together better. Cant adjust the drone sound to thin out the overtones. Very basic. Would expect more from a $1.99 app. ### 5/5 — Beatiful app straight to the point *2018-06-27, version 1.2.4* I was searching for such an app until I found it recommended by violinlab.com This app does what it’s supposed to do in a convenient way. Good job ### 5/5 — Great tool! *2017-11-05, version 1.2.4* I've used the web version of DroneTone tool for years,but app is more convenient. Playing scales and arpeggios against a drone tone is the best way to train your ear and develop a sense of the tonal center. The app doesn't have lots of frills, but it's easy to use and the cello tones sound great. ### 1/5 — Don't buy--no support *2017-09-21, version 1.2.3* I purchased this app yesterday; it doesn't work, and there are no instructions at all. I have contacted support but haven't heard from them. I want my money back! ### 5/5 — Great app! *2017-05-13, version 1.2.2* Works well for double bass, too! ## Frequently asked questions about DroneToneTool ### What makes DroneToneTool's pitches different from other tone generators?
