Sample text

Tromlitz (1791) felt that the flute was perhaps the most difficult of all instruments to play in tune. He thought that the natural unevenness of the tone, blowing too hard or too softly, an incorrect embouchure, improperly tuned flutes, and the placement of the holes in positions to accommodate the fingers, were all contributing elements. However, the flute can be played in tune if great care is taken to listen and to adjust. Quantz (1752, p. 55) believed that a good ear, among other things, can help overcome problems of intonation: It is true that the flute has certain imperfections in several chromatic keys.

It is our challenge to explore that expressive capacity. In this exploration, it is important to study the early flute tutors, for there is much to be learned. This text is full of references to the more important eighteenth-century tutors. However, we cannot simply mimic historical evidence, as ideas changed over the years and much of this historical information is conflicting. So in addition to studying historical references, the player will find it both necessary and rewarding to take cues from the flute itself and from its music, and to be influenced by the work done by players all over the world who have found a personal expression and brought this wooden flute to life in concerts and recordings.

Keep the little finger of the right hand relaxed and don't rest it on the flute when this finger is not in use. There is no need to keep the little finger extended in a ready-position to depress the key—such a position can only lead to physical problems. Some eighteenth-century flutists have dispensed bad advice regarding the placement of the little finger. Hotteterre (1707, p. " Corrette (c. 1734, p. " My advice is to ignore the advice of Hotteterre and Corrette. Keeping the hand healthy is a top priority.
