Advanced Ear Training Device 

One of the tools Rapvox uses to help students identify many musical elements is the rear training device from SIngPro it helps them to fine-tune their ear and " identify pitches, intervals, melody, chords, rhythms, solfeggios, and other basic elements of music, solely by hearing. The application of this skill is analogous to taking dictation in written/spoken language. As a process, ear training is in essence the inverse of sight-reading, the latter being analogous to reading a written text aloud without prior opportunity to review the material. Ear training is typically a component of formal musical training and is a fundamental, essential skill required in music schools."

What Is a Metronome?

A metronome is a device that produces a click at a regular interval of time. You can set how fast you would like it to go based on beats per second. Mechanical metronomes, which have been around for several centuries, have a pendulum that swings back and forth. You can also use an electronic metronome or even a metronome app on your phone.

Metronomes have been used for many centuries, but in 1815, the German inventor Johann Maelzel patented them specifically as a tool for musicians. Metronomes have been broadly used by musicians ever since.
