Practice three strategies for learning about early-music composers or works that you never knew existed.
You can discover composers and works through performers and ensembles specializing in early music, or through recently released recordings.
Try searching online for early music performers or ensembles and check their social media presence. For example, the renowned San Francisco early music ensemble Voices of Music recently tweeted about Nicola Porpora and included a link to a recording.
Search for recordings of early music online or in Naxos Music Library. For example, this Porpora piece is also in Naxos:
Classical music albums from the Naxos family of record labels, delivered through streaming audio. View recent additions to the Library. Access is limited to fifteen concurrent users.
News articles and concert or recording reviews written by music journalists are another way to learn about previously unfamiliar composers.
Search engines like Google and DuckDuckGo let you limit your results to view News articles. These results include publicity for upcoming concerts as well as stories about performers and ensembles - all of which could contain names of lesser-known period composers (as well as the usual big names, so be patient and keep looking)
If you run into online paywalls, try searching for the full text of your article in a library news database.
In this example, a Google search for "lute composers" turned up a news item from a British classical-music radio station, announcing an upcoming broadcast devoted to lute music by little-known composers.
Books in Armacost Library are excellent sources for names and biographical information on early music composers.
The Recent Researches series of scholarly scores publishes authoritative texts of music manuscripts by Renaissance and Baroque composers (as well as more recent periods). These are excellent scores to choose for your assignment!
Use printed bibliographies to discover lesser-known composers and masterworks beyond the core concert and recital repertoire. These books appear in the library catalog with the subject heading [genre] -- Bibliographies.
Several examples of printed music bibliographies in the library collection are presented here.
Alternatively, use Advanced Search to search subject headings related to musical genres or historical periods, such as:
motets
madrigals
part songs
suites
Renaissance music
Baroque music
This strategy will get you books of scholarly commentary as well as musical scores. Use the Resource Type limiter as needed.
In this example, a subject search for "madrigals" limited to scores turns up several Recent Researches volumes. Here's an example:
