Tuukka Jokilehto is a Finnish composer who specializes in easy piano music for beginners. He has a number of pieces for flute and piano that translate well for treble recorder. I have prepared digital accompaniments for the following pieces, arranged as a suite. You can find piano scores for these pieces and more at his MuseScore page.
