Vocal Exercises by Davengi is a flexible tool for vocal instructors, students and artists who need a convenient way to provide accompanyment for vocal warmups. It provides a wide range of pre-defined warmups as well as allowing custom warmups to be defined. A large number of vocal accompaniment patterns are included for use with both pre-defined and custom warmups. The vocal range for each warmup may be easily modified at any time. The application plays a series of musical patterns moving through scales to allow the full vocal range of the singer to be exercised. The scale range can be moved through chromatically or based upon a major scale. The range can be moved through going both up and down through the scales, moving only up or moving only down. The speed of playback can be adjusted on the fly ranging from 50 beats per minute up to 200 beats per minute. The vocal range indicators play the indicated note when touched so that the singer can verify and adjust the desired vocal range before the exercise is played.
