Flutist Emmanuel Pahud and pianist Eric Le Sage play arrangements of short pieces and songs by four German composers of the mid-19th century: Robert and Clara Schumann and Felix and Fanny Mendelssohn. Major composers of the earlier Romantic period somewhat neglected the flute as a solo instrument, even though there were a number of virtuoso players and the flute was popular with amateurs. The fact is that the instrument presented technical difficulties in terms of consistency of timbre and intonation. These were not satisfactorily resolved until 1847, when Theobald Boehm, a German manufacturer of wind instruments, produced the revolutionary prototype of the modern flute.
