Tonal it at’; Fr. tonal ité) The term Tonality, as contrasted with X2y, is distinguished by its broader significance and wider. Key denotes simply the mode (ofa piece) and the pitch of that mode; strictly, it refers solely to the harmonies constructed from the tones of its own diatonic scale. TONIC. 203 On quitting these harmonies, even by touching an ‘‘altered chord”, it trespa es on the domain of tonality; for— ere is the dividing line—sey embraces the diatonic harmonies referable to one tonic chord as the point whence they depart and whither they return, whereas tonality, taking this same tonic chord as a starting-point, includes any and every harmony related to it, so long as no actual change of tonic is brought about bya modulation. Tonality might therefore be briefly defined ‘as the chords grouped around and attracted by one central tonic chord, and thus appears as founded upon the relations of chords independent (in a measure) of key.
