SPANISH PIANOFORTE MUSIC
Played by NIEDZIELSKI
THE Foundations of Music on Monday and Tuesday are to be old Spanish Pianoforte Music. To the average Briton, that may well sound like a musical Mrs. Harris, and it would have been true enough, outside Spain, that 'there ain't no such thing' but for the enthusiasm of Joaquin Nin. Mo has collected a wealth of the early music of his own country which had lain buried in oblivion for decades, sometimes even centuries, and, from the examples which Niedzielski has chosen, it will be clear how well worth while the patriotic task has been.
Nin, as B.B.C. listeners have had chances of hearing for themselves, is himself a distinguished pianist and composer, a worthy disciple of Granados, who has done a great deal in the cause of contemporary Spanish art, too.

WEATHER FORECAST, SECOND GENERAL NEWS
BULLETIN

by NIKOLAI ORLOFF
FEW artists of the present day give such an impression of quiet, confident strength as Nikolai Orloff. His playing ranges from giant force to the most subtle shades of delicacy in the very way that his resolute and yet sensitive personality suggests. The programme ho has chosen shows his art in many such varying aspects.
A pupil of the Moscow Conservatoire in its great days, he won its gold medal at the ago of eighteen—the chief prize open to Russian students ; three years later, he was himself a professor there, having leave, however, to play in concerts throughout Russia, including one before the late Czar. Since 1922, when he left his own country, ho has played in most parts of Europe and America, winning friends and admirers everywhere.

Act III
The summit of a rocky mountain (Valkyrie Rock)
Relayed from THE ROYAL OPERA House, COVENT
GARDEN
Cast
Conductor, ADRIAN BOULT
THE third .act begins with the stirring Ride of the Valkyries, as the Warrior Maidens gather on their grim rock. Each of them has a slain hero across her saddle, whom she in bearing to Valhalla, but when Brunnhilde, the last to come, reaches the rock, it. is Sieglinde whom she is carrying. She hides Sieglinde in the forest, and then Wotan hastens to the crag in angry pursuit of his disobedient daughter. The sisters plead with him to spare her, but he bids them go, and the last part of the act is a splendid duet between the god and Brünnhilde. Gradually she recalls his former pride in her, and prevails on him to let her punishment bo less severe than he had first designed. She is to be laid to sleep on the summit of the rock with a great fire about her, so that none may come to her save a hero who knows no fear. The opera comes to an end with Wotan's splendid farewell as she is laid to sleep.
