In the Baroque period, the baritone voice was not yet well-defined, but many composers wrote vocal pieces with a range appropriate for the modern baritone voice. Composers used the general categories of soprano, alto, tenor, and bass for solo voice in their compositions. Johann Sebastian Bach (1685-1750) was no different from other Baroque composers in writing solo works to be performed by one of the four main voice types. The various ranges and tessituras of J. S. Bach's vocal works for bass solo voice are not limited to being sung by low basses, but may also be sung by more medium ranged baritones. The purpose of this research is to guide collegiate voice teachers and their baritone students in selecting appropriate repertoire from the works of Bach on the basis of each students' level of development and to categorize four groups of bass solos by Bach for collegiate baritone students: beginning level for freshmen, intermediate level for sophomores, advanced level for juniors and seniors, and pre-professional level for seniors and graduate students. This research was prepared in conjunction with a DMA lecture-recital of eight bass solos for collegiate baritone voice, selected from the study; two vocal works for each proficiency level.

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.
