is a CD I have. The sonata for horn and piano is rather unmemorable: it's from the area of Koechlin which I'd describe as diatonic and opaque. The other works are a rather different matter.
Morceau de lecture is a solo horn piece. Effective and idiomatically written. And he's not afraid of the high register, even on occasion (this happens elsewhere too) using pitches higher than concert F.
The
15 pieces op. 180 (1942) are mostly for horn and piano, c. 3-5 minutes in duration and the material is far more interesting and varied than that of the sonata. A couple of the pieces seem to use a quasi-systemic use of intervals (if that makes sense). Curiously, a couple of these pieces are for 4 horns playing entirely on the harmonic series.
The
Sonneries op.142 are for 2, 3 and 4 horns, again they're harmonic series pieces (the 11th harmonic seems to be the highest "out-of-tune" harmonic used) with often unashamed overtones (sorry) of hunting horn type of material. They are more imaginative than this description might suggest - bits of cuivre or antiphonal stuff and the last one features horns in unison. He seems to have got a bit of mileage out of this idea: Grove lists a couple of other sets of
Sonneries (30 in all), all described as being for "hunting trumpets" and also dating from the 1930s.
