 ### Negative Harmony is an app made to make the musical theory of negative harmony easier to understand and visualise.
 
+Easy to use, user-friendly interface:
+
 - Selection of all western scales and modes
 - Over 10 different chord types
 - Diatonic note detection / Indicator for notes/chords outside of the scale
-- Easy to understand UI design
 
 The app shows in a clear and easy way to understand what are the notes inside the chosen scale/mode and their relative negative harmony while also representing this inside the circle of fifths with the blue axis showing the relationship between each note.
