Check out fingerings at
http://www.wfg.woodwind.org/flute/ . Fingerings to G above high C (G7), as well as for piccolo, some alternate fingerings for flute and (important) piccolo, quarter-tone (

?!?-yes, some composers are writing these lol), and a link to Amazon.com to buy Pellerite's excellent book.

Make sure your high register up to C is very secure before moving above C. Trevor Wye tone book, or something like it, is good for this. Keep the tone hole uncovered about 2/3, and use lots of support!

Most practically, we should all probably learn fingerings to E; so far, this the highest I've encountered on several occasions each,
mostly the D, though. (F, one time, in a very quirky, contemporary piece), but the D# and E are a bit harder to produce than the C# and D. The D#, due to the acoustics of the flute, is INCREDIBLY unresponsive. (I have, literally 16 fingerings for this note, and only ONE works on my flute! Different for each of my students, depending on their instruments.)
