Ravel was a great composer, wrote in may different forms - his orchestra works are some of the greatest of the 20th century...
Daphnis & Chloe
Alborado del Gracioso
Valses Nobles et Sentimentales
Le Tombeau de Couperin
Pavane pour une Infante defunte
Ma Mere L'Oye
let's not forget the Piano Concerti, either...
are some of his best-known works...Ravel was a brilliant orchestrator, and his works present many challenges to performers to this day...Every orchestra's audition lists will contain a healthy portion of Ravel excerpts to be performed by prospective candidates.
As with Mahler, Beethoven, Mozart, Brahms, etc - most of the greatest conductors and orchestras have recorded and performed Ravel's orchestra works, which have long been mainstream elements of the standard repertoire...
for myself - I love all of these works, but my top favorites are
La Valse - the ultimate waltz, elegant, dark, sophisticated - which ends in a wild dissolution and frenzy [perhaps reflecting the state of the World at the time, which was ripping itself to shreds in the violence and chaos of World War I??]
Rapsodie Espagnole - brilliant writing, both colorful and flamboyant, and dark and mysterious..
Alborado del Gracioso - a short, brilliant work, colorful, with a contemplative, lyrical middle section - sandwiched by orhcestra brilliance.
Daphnis et Chloe - Ravel's magnum opus, imo -
I have many recordings of these splendid works - Monteux, Abbado, Munch, Bernstein - all good, but my top favorites, the ones I listen to most often - are
Reiner, and Martinon - they seem to bring out the colors, the flamboyance, the mystery, the subtlety, the great washes of sound most consistently.
I'm sure we have lots of Ravel fans here -
