Why singers are lazy
Singers have something of a reputation, and not always in a good way. They don't practise as much as instrumentalists - in fact, many of them confuse the words practice and rehearsal - a cardinal sin in my book.
I know that professional singers would argue that they simply can't - the nature of the instrument prevents them from practising six or seven hours a day.
But I am not talking about professionals, although some of this might apply to some of them, too. I am talking about choir singers, especially the ones that think they are doing you a favour, and aren't as good as they think they are. We have all met them.
I am led to think there is a deep problem here. When people compliment a singer they say "You have such a wonderful voice". This implies that the singer has a god-given gift. What does this do? It makes them lazy.
No-one says to a violinist "You have such a wonderful instrument.". They say that a violinist has a great technique, or that they produce a lovely tone, both of which imply that they have actually worked on it.
I am not a psychologist, but I am a teacher, and I know that a child rarely tries harder by being told they are naturally good at something. One must say, "You have worked hard to be good at this".
