Multiphonics are two or more notes sounding simultaneously. Video examples and production tips. Impedance spectrum of a modern flute with a B foot measured at the embouchure hole using fingering for the multiphonic C5 & D#6. Z is plotted in dB, i.e. Impedance spectrum of a modern flute with a B foot measured at the embouchure hole using fingering for the multiphonic A#4 with E5. Z is plotted in dB, i.e.

Acoustic schematic a closed tone hole an open tone hole Non-specialist introduction to acoustic impedance Non-specialist multiphinics to flute acoustics. Offermans recorded the etudes on the CD Daily Sensibilities. Offermans recorded all the etudes on the CD Daily Sensibilities. Acoustic schematic a closed tone hole an open tone hole. Using such a tools should first of all be enjoyable, stimulating your imagination and extending your possibilities for controlling your mouth cavity.
Initially there will be a lot of air, but with practice you can refine them. We may know the fork-fingering from the recorder. This is the standard fingering for D6 and may be compared with that for G6with the C hole acting as a register hole.
Acoustic measurements are available for these flutes – modern Bmodern Cclassical Cclassical Dclassical flaredbaroque Sound clips are available for modern Bclassical flared and baroque.
A fork-fingering on the flute creates an diffused and mixed ending of the vibration, so it will always create a less clear sound: But we will see that with the technique of multiphonic we can actually produce several fluet simultaneously. A two-note multiphonic requires the superposition of two standing waves whose frequencies, which are not in harmonic ratios, determine the pitches.
For this situation to apply, the frequencies of the notes have to be such that the effect of the inertia of the air in the open tone hole is large enough to allow some transmission past the mhltiphonics, but small enough to produce some reflection.
You need a constant airspeed and a wide angle at first that will let both notes in. Join and Register Now! The irony of these small-interval multiphonics is, at first, you have to unfocus to get the sense of focus.
For the Contemporary Flutist
Acoustics of baroque, classical and modern flutes. Flute 2 Multiphonics with pitches separated and then combined. Fingering a key depressed a key not depressed a part of the mechanism that is not normally touched Details in fingering legend.
Multiphonics within the harmonic series are usually easier with a “top-down” approach. For low-pitched notes, the tone hole is usually small.
modern B flute acoustics – multiphonic C5 & F#5
Multiphonics within the harmonic series are the result of overblowing into the harmonics above a fundamental pitch. Acoustic schematic a closed tone hole an open tone hole Non-specialist introduction to acoustic impedance Non-specialist introduction to flute acoustics.
With the bamboo tone topic we have learned that we can divide the fingerings of the flute into two categories: This short sample video is on Etude 5: Acoustics of baroque, classical and modern flutes.
Play a long note on the lower pitch. To compare flutes, it is easiest to open a separate browser window for each instrument.
Exercise for Singing Vowels. Fingering a key depressed a key not depressed a part of the mechanism that is not normally touched Details in fingering legend. A most fruitful Tool! The first line of advice on how to produce these comes from Robert himself, and can be viewed here.
The first two minima correspond to these pitches. I hope this has been of help. So with a total of now six open holes I have even more combinations of open holes available, which I all can manipulate directly with the finger or the thumb. The third, fourth and sixth minima can also be played.
Here is a 14 page booklet I put together on how to do the basics of some extended techniques: Typically, we have learned to regard the flute as a monophonic instrument, which can produce only one pitch at a time. You can hear multiphinics multiphonic C5 with F 5 played by Geoffrey Collins. Until the s, playing both notes together would have been regarded as a mistake rather than a multiphonic.
Here it is reflected to make the second standing wave. Multiphonics are two or more notes sounding simultaneously. Acoustics of baroque, classical and modern flutes. The wave travelling downstream from the reed is partially reflected at the open tone hole, which makes one standing wave. Play a long note on the higher pitch. Get a Skype Flute Lesson.
