Written in Rio in 1929, Choros #09 was dedicated to Arminda Noves d'Almeida in 1936.
For some reason Prof. Tarasti leaves Choros #09 out of his excellent study of the Choros series.
Villa-Lobos made a reduction for piano (the 56 page score is in the Museu Villa-Lobos). I haven't heard of any performances of this version, though piano versions of works also available in big orchestral scores (Amazonas and Rudepoema, for example) have worked out well.
Piccolo, 2 flutes, 2 oboes, eng horn, 3 clarinets, bass clarinet, 2 bassoons, contrabassoon, 4 horns,
4 trumpets, 4 trombones, tuba, timpani, tam-tam, bombo, tambor, tambor surdo, camisao (large and small), pio, triangle, reco, tartaruga, cax, cho (metal and wood), xylophone, vibraphone, celesta, 2 harps and strings
Published by Max Eschig, but I haven't come across a score in any of the stores or online library catalogues in which I've searched. There's a copy of the autograph score (148 pp.) in the Museu Villa-Lobos.
Here's a reference to a score in the Eugene Ormandy collection:
Villa-Lobos, Heitor. 1929. Chôros no. 9. Eugene Ormandy Collection of Scores. Paris: M. Eschig.
There are two excellent versions of this sprawling work available on the CD Choros 8 & 9 (Naxos) with the late Kenneth Schermerhorn conducting the Hong Kong SO, on Naxos (originally on Marco Polo, from 1994),
...and John Neschling conducts the Sao Paulo SO in this brand new disc from BIS.
Premiere: Rio de Janeiro, Orchestra of the Teatro Municipal; Villa- Lobos, cond; 7/15/1942
There's only one recent performance listed in the Villa-Lobos Concert database (August 2008).
