Elizabeth Walker’s book Baroque Flute Studies is a must-own for anyone looking to start playing the Baroque flute. It contains fingering and trill fingering charts, useful information on ornamentation, and excerpts, tone studies, and solos in each key. It also contains some of the most common Bach repertoire. It can be purchased here.
Janice Dockendorff Boland’s Method for the One-Keyed Flute is another indispensable resource for aspiring Baroque flautists. With extensive fingering charts, solo flute literature, and music taken from 18th century treatises, I can’t recommend this book enough. It can be purchased here or here.
I highly recommend sourcing a facsimile copy of Michel de la Barre’s Deuxieme Livre de Pieces Pour la Flute Traversiere Avec la Basse Continue. They’re quite wonderful little pieces that aren’t very well known. Be aware: you’ll have to transpose these. They’re written in a G clef that shows G on the first line of the staff, as opposed to the second line that flautists are used to. Being able to transpose facsimiles in a different clef is a useful skill for a Baroque musician to have, so do have a go! You can find a copy on IMSLP, or contact the Early Music Shop if you’d like your own hard copy.
Here are a few more exercises I use just to vary my practising, but that I also find very helpful for intonation and finger work:
Speed is not what you’re aiming for here! Practise these slowly, paying particular attention to intonation, phrasing, and smoothness of fingers.
I’ve found these to be especially useful for cementing fingerings and intonation. Its helpful for articulation, to practise them with ti (for short notes), di (for legato notes), and slurred.
