I recently watched a streamed performance by members of the Academy of Ancient Music. (Wonderful!) For an encore, oboist Leo Duarte played an instrumental version of the song, "Where'er You Walk" from Handel's oratorio, "Semele." I was unfamiliar with this piece but suspect that it is known by many musicians, as there is an arrangement for euphonium and concert band available.
"Where'er You Walk," a love song, has a simple but hauntingly beautiful melody and is available as a free pdf download for soloist and piano accompaniment in Bb (nice key for brass players) from IMSLP.org. It is also available as a pdf in any key from SheetMusicDirect. (My wife prefers the piano reduction of IMSLP.) I would encourage anyone interested in performing it to listen to Mr. Duarte's performance and note how his expert ornamentation adds to the beauty. https://www.youtube.com/watch?v=HATEkFyz0Z8
Kathleen Battle brings her considerable artistry to an excellent vocal version, also on YouTube.
Historical note: I saw some videos of "Where'er You Walk" performances during church services. Handel premiered "Semele" during Lent but may have received some criticism at the time due to the secular (pagan) nature of the underlying story.
