Tonality in music is the guideline of getting sorted out melodic pieces around a focal note, the tonic. For the most part, any Western or non-Western music occasionally gets back to a focal, or central, a tone that displays resonance (tonality). All the more explicitly, tonality alludes to the specific arrangement of connections between notes, harmonies, and keys (sets of notes and harmonies) that ruled most Western music from c. 1650 to c. 1900, and that keeps on directing a lot of music.
