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.

Non-specialist introduction to acoustic impedance Non-specialist introduction to flute acoustics. Also it will have the harmonic series as we discussed with Etude 2: The wave travelling downstream from the reed is partially reflected at the open tone hole, which makes one standing wave. multiphnics
For the Contemporary Flutist
A two-note multiphonic requires the superposition of two standing waves whose frequencies, which are not in harmonic ratios, determine the pitches. Please ‘like’ the page and share your thoughts and opinions.
In the Etude 5: Acoustic schematic a closed tone hole an open tone hole Non-specialist introduction to acoustic impedance Non-specialist introduction to flute acoustics. Play slowly and legato from the lower to the higher pitch. A fork-fingering on the flute creates an diffused and mixed ending of the vibration, so it will always rlute a less clear sound: This is a “bottom-up” approach to producing a Multiphonic.
We may know the fork-fingering from the recorder.
modern B flute acoustics – multiphonic A#4 & E5
Simply the amount of interesting fingerings is so much more extended on an open-hole flute, since we can also make use of the five small centre-holes and its combinations only the rim is pushed down, while keeping the centre hole uncovered. Now, halfway such brush movement, we change the brush-position or the direction, changing the image of the painted line.
Acoustic schematic a closed tone hole an open tone hole. Goge – a short extract of Shomyo, reciting by Japanese Buddhist monks, Japan. Avoid any additional lip-tension. Acoustics of baroque, classical and modern flutes.
To compare flutes, it is easiest to open a separate browser window for each instrument. Using such a tools should first of all be enjoyable, stimulating your imagination and extending your possibilities for controlling your mouth cavity. Basically throughout the piece, there are just two multiphonics on one breath-phrase.
For low-pitched notes, the tone hole is usually small. Play a long note on the lower pitch. Get a Skype Flute Lesson.
Even someone like me who has been familiar myltiphonics them for years needs to put in serious practice time on them. The third, fourth and sixth minima can also be played.
That may seem strange but sometimes it works. You may pass it on but please give credit where it is due. It is a good refresher! Also bear in mind that, depending on many factors, some pitches are microtonal and can be slightly higher or lower as indicated.
However, we should remember ourselves that we first of all want to use the multiphonic as a tool to develop. 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. While doing so, change the vowel from [o] to [ee].
In my Flute Talk article, I touch on the subject of small-interval multiphonics. The wave travelling downstream from the reed is partially reflected at the open tone hole, which makes one standing wave.
You can hear the multiphonic A 4 with E5 played by Geoffrey Collins. Concentrate first on the lower pitch, supported by the [o] vowel located in the lower part of the mouth cavity. An explanation of difference tones can be found in Wiki.
Here it is reflected to make the second standing wave. Join and Register Now! In Exercise D we simply transpose a multiphonic by moving the ‘acoustic ending situation’ up or mhltiphonics.
It may also be regarded as a C with enough cross fingering to flatten it by a semitone. Below are resources with extensive and complete lists of fingerings for Multiphonics: His advice is fantastic, spot-on and humorful, I recommend viewing it. In general it can be difficult, or extremely difficult, to perform a multiphonic with stability. To produce a Multiphonic, first extract each pitch of a Multiphonic fingering and the corresponding dynamic range of each note.
Bass Multiphonics in succession.
