PERFORMANCE NOTES / SPECIAL TECHNIQUES.

Piano/pp
Action:
ound:
Half harmonics
Notation: filled diamond note heads.
Half harmonics occur when the string is depressed by the left-hand finger somewhere between normal, stopped pressure and harmonic pressure. The sound is a mixture of the stopped string pitch, the harmonic pitch, and a resistant, slightly noisy quality. The stopped-string pitch is often also present in multiphonics. (…) [By] changing the pressure of the LH finger, the harmonic becomes more/less present. (Ellen Fallowfield, Cello Map, https://cellomap.com/multiphonics-other-multiple-sounds/)
Two versions in this piece:
1. pianissimo: soft, complex multiphonic timbre
2. forte: Aggressive, loud noise. Example on the youtube video titled: Half Harmonics | Cello extended technique | Hoechan Lee | ensemble blank (https://youtu.be/490IUWO1CBY?si=CqnVMU9zE1145aQT)
BOW ABOVE FINGER TECHNIQUES (B.A.F.) - CELLO ONLY
All cello B.A.F technques used are demonstrated in this video https://www.youtube.com/watch? v=geHbWjlGQ9k, see list of chapters on youtube.
B.A.F MULTIPHONICS
with or without glissando.
Place grip finger at a harmonic node in the area between sul ponticello - sul tasto. Place bow above grip finger. Keep grip finger and bow close to each other (approx 0,5-1,5 cm), Use (some) heavy bow pressure and slow bow and the result is a multiphonic sound. Not entirely overpressure. Intended result is a clear and complex multiphone (not pure noise although it s a little noisy, particularly on higher strings).
There are different «multiphones/chord complexities» depending on where you place the grip finger (sul tasto, ord, poco sul pont, etc.) Choose freely.
Single and double stop is used. Find your preferred interval to produce multophonics simultaneously on two adjacent strings.
«Bow position for bow-above-finger multiphonics
I find the best bow position for bow-above-finger multiphonics to be around a fourth or a fifth above the fingered note. Finger glissando is possible with the bow-above-finger multiphonics and the bow must be moved in proportion to the left hand.» (H. Thelin, Multiphonics on the double bass, 2011).
Glissando: both finger and bow shall slide. Keep bow and grip finger in parallel distance all the way.
Glissando: start as high as sensible (somewhere sul pont.too high doesn’t respond) and slide all the way down to natural stoppoint. - Possible to slide very slowly to have a long duration of the gliss.
B.A.F. HARMONICS
See the mentioned video for a performance illustration.
BOWING: Fast and light bow. The bow shall be placed close to the grip finger and parallel with the grip finger.
GRIP PLACEMENT: Normal harmonic pressure. Find Nodes on the string, there are many. (theory/chart: https://cellomap.com/) Dampening the neighbor string(s) may be . It is possible to glissando (let pitches pop out) instead of producing each pitch with separate bowing. T at the performers liberty.
SOUND: The intention of using this technique is to generate a specific pitch content (avoiding the recognizable natural harmonic series scale). The different strings respond differently, high strings have the «best» result the lower strings ar used intentionally. Some of the nodes produce pitches in other octaves than the majority.
The notation to show there is flexibility to follow your sound production process
NOTATION:
The bridge clefs render pitches unspecified. So the notation tries to show what direction to go, start/stop point, individual pitches, and durations. High placement = ponticello, lower - moves on to the fingerboard. No dynamics as there is not too much to go on, adjust to the context.
