The winner of the international Tchaikovsky Competition for Young Musicians when he was just 15 years old, Muller-Schott aims to spend at least two-three hours per day playing his cello.
It means he even plays while waiting in airport transit areas.
"When I stopped in Melbourne on my way here, I got it out and was soon surrounded by a group of children who were laughing and seemed to enjoy it very much."
He says his opportunistic practises seem to soothe fellow travelers, who will often strike up conversations about the music he plays and life as a celebrated concert musician. He describes his cello as his musical voice and says when he travels, he always books a second seat so it can be kept safely next to him.
"It is like a member of my family."
Its previous owner was US cellist Harvey Shapiro who owned the instrument for about 60 years. Shapiro was happy to pass it on, having heard Muller-Schott playing, and sent it with a gift of his favourite Havana cigars and a bottle of whisky.
Muller-Schott intends to continue this tradition, including a souvenir for whoever is the next recipient of the 290-year-old cello. However, he says that could be a while away yet because he intends to keep his faithful friend for the next few decades.
"If I could keep it for 60 years, I would be doing very well."
Muller-Schott plays with the NZSO on a five-city Schumann & Barber concert conducted by fast-rising US conductor James Feddeck,
