As lirico-spinto soprano commonly indicates a soprano with a heavier voice than lyric soprano and a lighter voice than dramatic soprano, there are many problems in the assessment of the voice type. Lirico-spinto soprano is characterized differently by various scholars and sources offer contrasting and insufficient definitions. It is commonly understood as a pushed voice, as many interpret spingere as ‘to push.' This dissertation shows that the meaning of spingere does not mean pushed in this context, but extended, thus making the voice type a hybrid of lyric soprano voice type that has qualities of extended temperament, timbre, color, and volume. This dissertation indicates that the lack of published anthologies on lirico-spinto soprano arias is a significant reason for the insufficient understanding of the lirico-spinto soprano voice. The post-Verdi Italian group of composers, giovane scuola, composed operas that required lirico-spinto soprano voices. These giovane scuola composers include Alfredo Catalani (1854 –1893), Umberto Giordano (1867 –1948), Pietro Mascagni (1863 –1945), Giacomo Puccini (1858 –1924), and Riccardo Zandonai (1883 –1944). Descriptions of the soprano voices that premiered these roles are included in this document to determine the suitability of the lirico-spinto soprano voice for each role.
