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.

Multiphonics within the harmonic series are the result of overblowing into the harmonics above a fundamental pitch. That is difficult to do when you are blowing in two directions at once.
Multiphonics within the harmonic series are usually easier with a “top-down” approach. The third, fourth and sixth minima can also be played.
Acoustic measurements are available for these flutes – modern Bmodern Cclassical Cclassical Dclassical flaredbaroque Sound clips are available rlute modern Bclassical flared and baroque.
This is a “bottom-up” approach to producing a Multiphonic.

Imagine the [ee] located in multi;honics higher part of the mouth cavity. In the Etude 5: To play a diminuendo of a Multiphonic, the highest or lowest note of the “chord” should be the reference tone and played to the end of the diminuendo. Here is a 14 page booklet I put together on how to do the basics of some extended techniques: Acoustics of baroque, classical and modern flutes. From Harmonic to Multiphonic.
Multiphonics with pitches separated and then combined. Strive for such calm and natural atmosphere throughout the piece. There are two basic types: They will sound focused and rich because of the very low difference tone caused by a close interval.
For low-pitched notes, the tone hole is usually small. Multiphonics are not really harmonies or chords but rather color effects on a note.
Until the s, playing both notes together would have been regarded as a mistake rather than a multiphonic. A fork-fingering on the flute creates an diffused and mixed ending of the vibration, so it will always create a less clear sound: In that way, we may experience the multiphonic not as just two simultaneously flutee, but as a most attractive sculpture, as an object of sound. Fingering a key depressed a key not depressed a part of the mechanism that is not normally touched Multiphonids in fingering legend.
If we compare this to painting, we may imagine each phrase like one slow brush movement. Then, keeping a constant airspeed, use the angle of the air to find both notes. Non-specialist introduction to acoustic impedance Non-specialist introduction to flute acoustics.

Next you will find a variety of some interesting multiphonics to study in Exercise C. Any further suggestions are welcome.
The first line of advice on how to produce these comes from Robert himself, and can be viewed here. Also it will have some unexpected series of harmonics, totally depending on the exact fingering and there are thousands of fingering possibilities!
With the bamboo tone topic we have learned that we can divide the fingerings of the flute into two categories: With the bamboo tone topic we have learned that we can divide the fingerings of the flute into two categories:. In my Flute Talk article, I touch on the subject of small-interval multiphonics. A two-note multiphonic requires the superposition of two standing waves multipohnics frequencies, which are not in harmonic ratios, determine the pitches. For flutd notes, the tone hole is usually muultiphonics.
The wave travelling downstream multiphonic the reed is partially reflected at the open tone hole, which makes one standing wave. Acoustic schematic a closed tone hole an open tone hole Non-specialist introduction to acoustic impedance Non-specialist introduction to flute acoustics. 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 hole, but small enough to produce some reflection.
Goge – a short extract of Shomyo, reciting by Japanese Buddhist monks, Japan. Working on Shun-San got muliphonics thinking about small-interval multiphonics those with an interval of an augmented second or less. For similar reason I actually had opened my left-hand thumb-key on my 18K Kotato flute, to create an ‘open thumb key’. While doing so, change the vowel from [o] to [ee].
Play the upper Harmonic with the minimal possible support and lips forward and relaxed, until the bottom note s come into the sound. Basically throughout the piece, there are just two multiphonics on one breath-phrase.
Use the vowel [ee] to support this sound.
I hope this has been of help. In exercise B we see two samples with each the four basic steps to study.
