📚 What is Diatonic?
Diatonic refers to notes, intervals, chords, or melodies that derive from a standard major or minor scale without chromatic alterations. Think of it as staying within the 'family' of notes belonging to a key. It's the most common and 'natural' sound in Western music.
🎶 What is Chromatic?
Chromatic, on the other hand, involves notes, intervals, chords, or melodies that include notes outside the diatonic scale. These notes are often indicated with sharps (#) or flats (b) and add color, tension, and expression to the music.
