Key Points of Focus:


1) Bow Articulation - 
beginning and ends

Pauk - gesturing for the beginnings of notes and also showing bow separation repeatedly
Kless - describing accents, with gestures
Kless - showing different articulation on the first note of the first movement

2) bow articulation -
separation/connection
portato/legato

Pauk - a typical example of his 'lift the bow!' comment
Kless - showing bow action, as it relates to weight. Shows relationship between bow action and vibrato. Reiterates idea of bow flexibility.
Pauk - singing and demonstrating decisive  articulation. Gesturing as I play
Kless - shows more playful, less accented approach. More connected.
Kless - showing flexible bow action between notes. More flexible bowing 

3) left hand articulation

Pauk - shows expressive fingering. Says opening is 'too flowy' - shows relation between bow speed, weight, and left hand action. Shows slow bow action, raising the arm on the up bows, and downwards on the down bows. Wants slower bow. Again, relation between bow speed and vibrato. Excited gesturing near the end.
Kless - shows great variety of bow speed. Vibrato is too late (delayed on each note)
Kless - unhappy with audible shifting. Shows more variety of shifting. The combination should be very creative.
Kless - not relaxed enough. Gestures relate to relation between left hand and bow.

4) physicality:
set-up, use of bow
speed and weight

Pauk - showing articulation with very little bow.
Kless - sound not rich enough. Seems to be because of weight/speed/left hand relationship. It sounds too horizontal and macho. Needs more roundness. The language needs more ups and downs, more expression, and more freedom.

5) clarity

Keller - sings with more waves and not as sustained. Wants me to 'find the notes' before adding vibrato (to do with clarity of sound) Details of musical line.
Keller - clarity in intonation, sound, and articulation. Fingerings in the lower position for increased clarity. Concerned with resonance.

6) musical expression

Pauk - more 'gypsy band' character in cadenza.
Kless - wants a different character for this section. More mysterious.
Pauk - more excited feeling in piu mosso. Separation and lifting between notes and phrases. Demonstrates more decisively.
Keller - 'mourn' more in the opening. Sound is too even. Need to explore the notes and 'what they want'. More waves.
Kless - too classical and too sliced.
Keller - needs more flexible sound. Should be absolutely classical. More speaking. Needs to be powerful but not aggressive, and he feels it is his mission to defend this music.

7) language/parlando

Pauk - combination of many types of articulation.
Kless - technical details that allow the music to speak more. Speaking tied to minute technical control and details.
Keller - more flexible sound. Needs to sound classical. More speaking, less passion.
