These notes (from B5–A6) sound almost exactly the same as the regular piano or pianissimo notes.ĭ7 requires a forced attack, while the notes above it as far as F7 can only be produced with extreme force and are therefore not called for in orchestral literature. The harmonics which are less often called for can be played by overblowing to the 4th natural (2 octaves above the fundamental). Exceptions are made in difficult passages, however, where it is not unusual for the notes D6 through A6 to be produced by overblowing to the 3rd natural (twelfth). Dissipative losses vary significantly with the frequency of oscillation and the. An open hole at a pressure node can radiate as a dipole when (b/a) is large and (t/2b) is small. It is designed to preserve as much virtue of traditional clarinets as possible, while its natural appearance is hardly distinguishable from conventional all-wooden models. Thermoplastic ABS resin is injected into the cavity, instantly forming the inner shape of a clarinet.
#Air columns and tone holes series#
The high notes are generally produced by means of special fingerings rather than by overblowing. When the fundamental plane-wave mode of the main air column oscillation is at a pressure node, both the open and closed hole series impedances are negative inertances whose values depend on the tone hole proportions. The upper joint body is drilled out slightly larger around the bore and tone-holes. By replacing it with a B footjoint B3 becomes playable as well (although the higher notes do not respond so well on this footjoint).īy overblowing to the 2nd natural (octave) the range Eb5–D6 becomes available: The footjoint is detachable the C footjoint is standard and contains the tone holes for the low notes from Eb4 to C4.

With the aid of the keys the notes from B3–D5 are played starting from the fundamental (1st natural). This means that flutists mainly use naturals 1 and 2 and only rarely naturals 3 and 4. It is primarily the keywork that is used for sound production, whereas the technique of overblowing, so important on brass instruments, plays only a subordinate role on the flute. The flutist compensates for these differences by means of the embouchure.

There are so many flutists, so many different embouchures and consequently so many different means of expression.īlowing strongly results in a higher pitch than blowing softly this is true of all flutes. The shape of the lips, the position of the upper lip in relation to the lower lip, angle of the embouchure etc. It is the flutist’s lips that play the most important role attack on the flute is highly individual. The sound is projected through the open lower end and the open keys.

low notes is a function of direction of the air column. The flutist uses tone holes and keys to shorten the vibrating air column, thus producing an increase in pitch. If you cover the tone hole with both lips and blow all the air into the flute.
#Air columns and tone holes generator#
This cyclically vibrating air stream is the sound generator and excites cyclic vibrations of the air column inside the flute’s cylindrical tube. Many instruments have holes, whose opening and closing controls the effective pitch. Sound is produced on the flute by blowing: the flutist blows through the mouth hole (embouchure hole) and the stream of air that makes contact with the edge is cyclically directed outward and inward. Wind instruments produce sounds by means of vibrating air columns.
