Mas que ano este de 1911!

We Futurists proclaim that the diverse modes of old scales, the various sensations of major, minor, augmented, diminished, and also the very recent modes of scales for internal tones are none other than simple details of a unique harmonic and atonal mode of a chromatic scale. We declare, moreover, that the values of consonance and dissonance are non-existent.
