"MetroDrone" provides a unique system for learning ear training for practical application to transform your sense of key and time. Learn how to think the same way you hear.

The main purpose of the MetroDrone is to get you always thinking in the tonal center of the key regardless of what chord you are playing.

Simply learning modes will not teach you this concept. If you practice a C scale with a C MetroDrone going on in the background you are thinking about a C scale and you are hearing it in relationship to the key of C. This gets progressively more important as you work with more and more complicated material.

MetroDrone is Bruce's best-selling product of all time for the course's excellent ear training techniques!

Instructor Bruce Arnold has 30 years of experience teaching music from beginning to advanced students.
