How does anyone know then what instrument is their strength, and what they want to do without giving it a go?
Do I get her to learn piano just because it is good coordination with the hands, and enables her to learn both clefs, and she enjoys the fact that it's a complete piece by itself, it doesn't need other instruments? But if she only learns piano, she can't join an ensemble, she can't join a marching band, she can't join the orchestra.
Do I get her to learn woodwind just because it is the easiest one for her to play, that she gets instant success from it, she can join the orchestras and ensembles? But she can't read bass clef just with woodwind, very few marching bands with woodwind etc.
Do I get her to learn brass just because she thinks it is the most fun to play, and she can join the orchestras, ensembles, marching bands, and play bass clef? But it doesn't sound as good to her playing by herself as the piano does?
How do you know which instrument is the one to specialise in until you have played a variety of instruments?
My older children play an array of instruments, and love them all, are not going to make a career in music, but love to play them in the different settings. It's great that when there's something that they need a woodwind instrument for, no problem they can partake and have fun.
For my older children it's the same with sport, they could do 25 hours a week of swimming, they could do 15 hours a week of gymnastics, they could do 8 hours a week of hockey, they could do 8 hours a week of netball etc. But they don't as that would mean they have to choose one, so they do a couple of hours a week of each sport, and complete at regional/county level in them, and represent the school in them. But they are never going to be professionals in sports, because they haven't specialised.
They do not suffer from anxiety.
