We should let the notes lead us, rather than us guide them
In 1990, after the Keller Quartet won the Evian and Borciani competitions, we received plenty of concert invitations. Composer György Kurtág suggested that we stop performing for a year in order to become immersed in our own work, and to find ourselves. I would certainly listen to him today and undertake fewer concerts. This might not be financially profitable, but it really is worth it.
I would read more scores. Nowadays, many youngsters listen to CDs of famous musicians and try to imitate them. This is natural, but it’s better if players discover pieces for themselves. I deeply believe we should let the notes lead us, rather than us guide them. It would also have been very useful to study composition, and I would recommend starting that as early as possible.
