Her father was waiting for her, and on their way to the station she could see that he was absorbed in her art of singing. His remarks were occasional and disparate, but she guessed his train of thought, supplying easily the missing links. His praise was all inferential, and this made it more delicate and delicious. On bidding him good-night he asked her to come to choir practice. She would have liked to, but her accompanist was coming at half-past ten. There were few days when she was not singing at night that she dispensed with her morning's work. She considered herself like a gymnast, bound to go through her feats in private, so as to assure herself of her power of being able to go through them in public. Even when she knew a part, she did not like to sing it many times without studying it afresh. She believed that once a week was as often as it was possible to give a Wagner opera, and even then an occasional rehearsal was indispensable if the first high level of excellence was to be maintained. With her morning's work she allowed no one to interfere. Owen was often sent away, or retained for such a time as his criticism might be of use. But to-day she was expecting Ulick; he had promised to go through the music with her; so when Merat came to tell her that the pianist had arrived, she hesitated, uncertain whether she should send him away. But after a moment's reflection she decided not to forego her serious study of the part. She only wished to talk to Ulick about the music, to sing bits of it here and there, to question him regarding certain readings, to get at his ideas concerning it. All that was very interesting and very valuable in a way, but it was not hard work, and she felt, moreover, that hard work was just what she wanted before the rehearsals of "Tristan" began; there were certain passages where she was not sure of herself. She thought of the cry Isolde utters in the third act when Tristan falls dead. The orchestra comes in then in a way very perplexing for the singer, and she had not yet succeeded in satisfying herself with those few bars. "Tell the young man that I shall be with him in half an hour."
