The kids and I found this biography quite engaging, as is typically the case with Opal Wheeler's writing. The connection to a pet rabbit named Paganini within a series of audiobooks (Karina Yan Glaser's Vanderbeekers series) was also quite fun.
Engaging story-telling and lovely writing about Nicolo Paganini's life, violin playing, music-making and travelling around Europe meeting other composers and musicians, dignatories and royalty. Great book for kids aged maybe 7 to early teens, irrespective of whether they're studying music or an instrument.
