Hey Binh, it is mistake-free, clean. The rhythm is stable, difficult measures are performed perfectly. The thumb attack is quite strong, but I'm a bit concerned that moving the hand might hamper simultaneous p-i, p-m or p-a strokes. Is it comfortable for you to play variation C? Is your thumb attack as strong as in variation A?
Very good work, Chu! You played it well and complete without long hesitations between the different sections. You are also able to get a strong sound from your i m alternations in the triad arpeggios. I think that if you continue to memorize it (if that's a goal) and play it once in a while, it should get smoother.
Hi Binh, I like the sound of your playing this piece. I agree with Andrei's observations that you have a steady rhythm and clean notes. I also think that your LH is good at sequential planting for the chords, which in this piece works well because the RH is playing arpeggios.
Having watched your video several times, I think the hand movement comes from playing the thumb stroke by using a wrist movement (as in strumming), instead of by using the respective hand muscles. I'm including a video that I found very informative. From around 5:30 to 6:45, Gohar talks about that specifically, but it is worth watching the whole presentation.
Interesting, is this muscle involved much? It supposed to move the shoulder upwards/backwards, right? Not sure, but is the the combination of guitar angle and how low/high it is against your body correct (for your anatomy)? For example, Xavier Jara (GFA 2016 winner) holds the guitar body pretty low, but the angle is extremely high so that it is almost vertical. Pepe Romero holds the guitar high, so that he can rest his chin on it.Binh NguyenKhac wrote: ↑Mon Nov 27, 2017 11:14 amThank you everyone for your comments.
Everything is connected now. I rotate my thumb, making my whole right hand unstable. Why I have to rotate? Because with my sitting posture, my right thumb doesn't have a good "striking zone" as Chu wrote. I tried classical posture today and found out that my right thumb attack was louder and even effortless. But there is a problem, my left shoulder is tired and the muscle in the picture hurts. I only can practice 10 minutes before it becomes unbearable.
Have you guys ever had this problem before?
