I’m playing a Concert flute in w Brass and Woodwind band and we play a lot of types of music. I’ve taught myself to played the keyed C flute and need to know which keys to trill with. Ornamentation was fine on the whistle and on the dixon flute but I am having problems trilling 3rd Octave Db and Eflat. I have a good flute with 2 trill keys but no idea how to use them. Can anybody advise me or give me a url to a page on the web thanks. 
Thanks a lot.Much easier than I thought. 
That is the upside to all of those buttons!
