In the evening I was in Diaghilev's box for the second performance by the Ballets Russes (they perform three times a week) and saw the Chant du Rossignol, the ballet fashioned by Stravinsky from The Nightingale*. I listened with tremendous interest, especially to the orchestration; as for the music there is much that is interesting, but also much that is redundant scratching. I must hear it again. The Rite of Spring, when Stravinsky and I played it four-hands in MIlan, produced a far stronger effect on me than this ballet. Massine's staging is very effective and imaginative; he is a gifted choreographer. Picasso's designs are very effective in places, but are sometimes inept.** Picasso himself was in the box, but in the general mêlée we were not introduced and it was only afterwards that I heard it was he. Stravinsky was distracted and in a bad temper, as he claimed the orchestra played badly and had not properly learnt the score.
