The unconventional note is the G flat. A composer of the previous musical generation would certainly have written G natural. The reason is that a long succession of whole steps is contrary to the spirit of the diatonic scale, upon which the classical musical system is based. The diatonic scale contains two half steps within the octave, thus giving to the succession of notes variety and to the scale itself individuality. The four notes which Fauré here uses are the only four adjacent notes in the scale which do not contain a half step. Even such a sequence without a half step was too long to suit the older composers. This sequence was to them the awkward place in the scale. It was within the letter of the scale but contrary to its spirit. So the older composer would have changed the G flat to G natural and would have felt a distinct gain in grace and fluency. Perhaps Fauré used the G flat only because it was different. He may have started his experiments purely in a search for variety. But he soon saw its possibilities. For this increased use of whole tones develops logically into the whole-toned scale (without any semi-tones and hence without any existence as a tonality). And this whole-toned scale is one of the chief features of the modern French music. But in addition to its melodic significance this bit of unconventionality on Fauré’s part had deep harmonic significance. For if the identity of the diatonic scale is destroyed the whole system of classical harmony falls down. Without a definite scale you have no tonic for your harmony to centre around. And your harmonic scheme loses all its value as a system and reduces to a use of chords for themselves (that is, their sensuous value) or for their relation one with another. When you have done this your whole musical basis has changed and a new musical world has come into being.

This first timid attempt on Fauré’s part was rapidly followed by other experiments, still cautious but logical and continuous in their direction. In the song entitled ‘Lydia’ we have the following opening phrase:

Lydia sur tes roses joues Et sur ton col frais

Here the tonality is disturbed not only in the melody but in the harmony also. Without preparation or warning Fauré disregards the half-step (B flat) which would have kept his music true to the diatonic, plunges apparently into a new key. But the change is not truly a modulation; the new key is really not a key. For the persistence of the F in the bass is a foreign element and shows that Fauré was not aiming at modulation at all. What he was aiming at was color. It is significant that the ‘color’ accompanies the words roses joues. This gentle dislocation of our conventional harmonic sounds like a blush translated into tones. Fauré had discovered modern ‘atmosphere.’

From now on Fauré’s experiments in this sort of thing become more frequent and more radical. In ‘The Absent One’ he uses ordinary suspensions for their atmospheric effect. Other songs of the same period—among which ‘Silvie,’ ‘After a Dream,’ ‘Barcarolle,’ and ‘Over There’ are the best—show traces of the development. ‘Nell,’ in opus 18, shows an increasingly delicate feeling for the inner voices in the accompaniment; the broken chords that support this melody are not a mere harmonic support but a delicate weaving of suggested voices. The ‘Traveller’ shows increased power and vigor. The ‘Lullaby,’ in opus 23 (one of his best songs), shows an attempt to get color by means of regular suspensions and dissonances, secondary seventh chords, and the like, all permitted in the old system but employed here with a special emphasis which is unescapable. ‘The Secret,’ in the same group, shows a similar attempt. The Chanson d’amour in opus 27 should be mentioned in passing.

In opus 39 we find the beautiful song, ‘The Roses of Ispahan.’ Here Fauré uses exactly the same harmonic device that we have pointed out in ‘Lydia,’ but this time with more confidence:
