Jaques Fevrier, a French pianist as yet unheard in this country will appear as soloist in Ravel's Pianoforte Concerto for the Left Hand, as the Boston Symphony Orchestra presents the sixth pair of concerts of its season in Symphony Hall on Friday afternoon and Saturday evening.

M. Fevrier, who made a special study of the score with Ravel, performed it a fortnight ago in Paris with considerable success, Ravel being present. He has been invited to come to America and appear in the work with this orchestra in Boston and New York.

The Concerto was written for Paul Wittgenstein, the one-armed pianist, and had its first American performances by him under Koussevitzky's direction in 1934.

It seems to be no fatal drawback for a pianist to lose his right hand. There have been written for the left hand alone four good pieces with opus numbers by Reger; two finely conceived and well-placed selections of Skriabin, opus 9; etudes by Moszkowski, Saint-Saens, Berens; and also Brahms has set Bach's Chaconne in D minor for violin alone as a study for the left hand.

The little Symphony in A Major, which Mozart wrote at the age of 18, and which was introduced by the Boston Symphony last year, will be repeated. The program will conclude with Strauss's tone poem, "Ein Heldenleben."

Other Concerts

Concluding its series of six concerts, the State Symphony Orchestra will present Tchaikowsky's Symphony Pathetique in Sanders Theatre Sunday evening. Alexander Thiede will conduct.
