My current recorder reportoire is the first piece from Suite 3 of the Water music by Handel, and "Thou Didst Not Leave His Soul In Hell" from Handel's Messiah. I love how those sound on recorder, with trills and ornaments. I also play the the instrumental part of "Jesu, Joy of Man's Desiring", and the theme from Dvorak's Slavonic Dance in E minor (Op. 46?#2). That last one is one of my all-time favorites.
With flute I am playing simpler things right now. I had been playing Gluck's Dance of the Blessed Spirits, and a couple others I can't remember, but the G key mechanism became slightly bent making many of the notes not work, and I didn't know what it was and wasn't able to get it looked into. Anyway, I am back to playing the flute but I still have a little ways to go to catch up to where I was

I am practicing the opening theme of Tchaikovsky's Swan Lake Suite. Mainly I need to strengthen my lungs again and practice good breathing. The high notes on the flute take more wind than any instrument except the tuba!
