Lessons Workspace

Practice makes perfect. Learn how to play a musical piece at your own pace. Lessons can be slowed down or pitch changed to suit your needs. You can even scroll a music passage and capture the chords.


Modes Workspace

This Workspace is an amazing tool for expanding your music theory. Each mode has a very distinct sound; for example, the Phrygian mode sounds melancholy and reflects the music of Spain. The Lydian mode sounds happy and is often used in jazz and rock music. The Mixolydian mode evokes a bluesy sound and can often be heard in jazz, blues and rock music. The Locrian mode, on the other hand, has a very strange sound but is rarely used.

This Workspace provides an interactive way to learn what scales are associated with each mode.


Scales Workspace

A scale is a sequence of notes arranged in order, tones, or semi-tones dividing what is called an octave. Tap on either the root note or chord type button to select from a series of Music Scales. These scales are useful for a musician playing any kind of music.
