The high note is not the only thing.
But I won't deprive myself of singing opera as long as my voice follows.
Young singers are much better educated musically, much better informed, through discs and videos, than I was.
I will prove that a great conducting career is expecting me.
To stay at my best, I have to stop talking during the preceding day.
With my personal preparation at the piano, I can afford to hum at half voice.
