I'm new to the flute (the flute I picked up secondhand off of eBay arrived today!), but not a newcomer to music. Years (~6) ago, I used to be reasonably proficient at the clarinet, but I've decided to take on the challenge of a new instrument.
I don't plan on taking lessons immediately, so I'm looking for a good lesson/drill/method book series. I can already read music, and I don't seem to have much trouble producing notes including low C, so I need a series that will have lots of drills but will progress relatively quickly, and is appropriate to an adult learner.
I like the Rubank series because of the way they progress along with scales, etc. Better than any method book is a few lessons with a competent teacher.
I tend to shy away from books that have lots of photos showing how to hold and play flute as they tend to often show incorrect posture.
I absolutely hate "E. Wagner foundation to flute playing" which means it's really good book. I hate it because it's tough but it really gives you a good work out on the flute. If you like a book then maybe it's too easy. Anyway I have been working out of this book for a year and it has helped me more than some of the easier books I have.
It might be a good idea to start out with a rubank book, the difficulty progresses as you get further in the book, and you can work on scales, aprpeggios, etudes, there's finger exercises, basically a good assortment of neccessary materials.
