Introduction - Music Charactersistics

Music is all about sounds and rhythms. Keys are groups of notes and chords that form a scale and a range of sounds. Each key has a unique set of notes and unique set of chords. Notes played sequentially form the melody of a song. Chords which are made up of three or more notes played in unison, form the harmony of a song. It is the mix of melody, harmony and rhythms that add richness to a song. . 

We have two music apps in the App Store.

 - MScales: This app describes the scales (notes) in each of the major keys. 

 - Keys-Chords: This app describes the chords in each of the major keys. 

In addition, each app has a Transpose View that shows you how to transpose, (to convert) your music from one key to another. (i.e. from the key of C to the key of B ♭ . )

Use the links on the top of the page to take you to a description of each app.
