Definitions

• the presently disclosed subject matter relates generally to the field of teaching, learning, and improvement of musical instrument pedagogy and more particularly to a device, system, and methods for indicating trombone slide positions.
• the trombone is known to have a relatively long learning curve compared to other instruments such as piano or saxophone. This is due to inherent difficulties in playing the trombone posed by its design.
• the trombone is a brass instrument. At their core, brass instruments produce sound via vibrations of the lips powered by the expiratory respiration muscles.
