To me success can be both artistic and professional and I believe it is important to make this distinction. This said, I feel the best success I wish to have is to artistically fulfil my aspirations and, because of that, be admired and respected by audiences and musicians alike. Fingers crossed!
My greatest challenge is ongoing: showing everyone that the double bass can be a soloistic instrument and can hold its own in the musical world.
I think success for a musician is finding a way to evoke emotions in your listeners. If you’re able to connect with yourself and your audience, in my opinion, you’re a successful artist.
