One of my favorite combinations of musical instruments is flute and classical guitar. I especially enjoy music for flute and guitar since my daughter plays the flute. She and I often play music together. Many of the duets we play are pieces I have arranged or transcribed.
I have added to my website a few of these transcriptions and arrangements. They include music from the Baroque (Telemann and Vivaldi), folk music, and a setting for Christmas of “Cantique de Noel” (O Holy Night).
You can download any or all of the sheet music for free:
