Range, tuning, sound and playing techniques of the flute for composers and arrangers. The C flute is the higher instrument of the woodwind family. It is tuned in C and is written with a treble clef, at real pitch. It is tuned by modifying the length of the tube. Its range goes from the C2 note below the stave, up to the C5 note, five ledger lines above the stave, and sometimes higher. The bass register is quite rich in overtones, the medium register is rather dense, soft and full, and the upper register is clear and bright, sometimes whistling in the extreme. As with all wind instruments, the musician's breathing is very important, especially in the low register which requires more air. The detached playing is organized around three major articulations: simple, obtained on the letter "T", double, obtained on letters "T" and "K", and triple, obtained on the three letters "T", "K "and" T ". The flute can produce special effects such as: the "staccato", "legato", the "flatterzungue" obtained by rolling the tongue, and the "trill", a rapid alternation between two adjacent notes.
