Paravicini was born extremely prematurely, at 25 weeks. His blindness was caused by oxygen therapy given during his time in a neonatal intensive care unit. This also affected his developing brain, resulting in his severe learning disability. He also has symptoms of autism.
He has absolute pitch and can play a piece of music after hearing it once. He began playing the piano by the age of two when his nanny gave him an old keyboard. His parents arranged for him to attend the Linden Lodge School for the Blind in London. On his introductory visit to the school, in the music room he broke free from his parents, then headed straight for a piano being played, and then pushed the player, Adam Ockelford, aside to take over. Ockelford encouraged him and arranged first weekly and then daily lessons. Aged seven, Paravicini gave his first concert in Tooting Leisure Centre in South London.
