This recording gathers, for the first time, the complete original compositions for the organ by Giacomo Puccini. It is thanks to the musicological efforts of the Giacomo Puccini Study Center in Lucca that, between 2015 and 2017, many of these compositions for the organ resurfaced. They had been scattered across various collections. Altogether, there are 57 pieces composed between 1870 and 1880, during the period when the young music student served as an organist in Lucca and neighboring towns. The origin of these pieces comes from Puccini's decade of regular work as a liturgical organist and from the lessons he gave between 1874 and 1878 to Carlo Della Nina (1855-1918). Puccini displays a variety of styles mirroring the diverse content and liturgical function of his creations, from the shortest movements whose size is determined by liturgys pace, to the true masterpieces like his Three Sonatas.
