If you have a successful track record it is easier to get people to buy-in to what you do. How do conductors demonstrate this at the outset of their career? One common way is to do well in a conducting competition. It is also possible to show that you have a successful track record in a closely related context – an orchestra or band will often regard a well-known soloist or experienced high-level player as having skills relevant to the field of conducting.
Again, the series of interviews with early career conductors in the Careers Office is a good place to explore this topic in more detail.
You might find it interesting to do some research on some of your favourite conductors: read the biographies on their websites to see how they got started and try to figure out how they build up their own unique track record of success – every journey is different!
