What she did she learned to do well.

Even Herr Brachmann was often charmed by the delicate originality of her touch, which proved that her own thought and feeling were infused into the music before her.

With her increasing vigor was gained the ability to use her vocal organs in sustained effort.

He guarded her carefully against over-exertion, and her advance was assured and safe.

Note after note, true, sweet, and strong, was added to the compass of her voice, and this exercise reacted with increased benefit on her general health.
