Dear Jim Woodhouse and Paul Galluzzo ,
The article titled "why is the violin so hard to play" is really wonderful and many thanks for the same.
I have tried to play the violin, Guitar and the piano and find the limitations and difficulty are based on the capacity and passion of each individual. Sight reading is most difficult in the piano and demanding.
Many do not know how to bring out the dynamics and still could pass off as a pianist in the presence of a musically naive audience .
Guitar was the easiest to impress ,within a few weeks of picking up the instrument. However to play like the greats such as Chet Atkins is another story.
The violin seems to be easy if you do not do not know what to expect from it. The tones produced varies from country western through jazz ,Irish and classical western. Not forgetting Chinese ,Indian [South and Hindustani] .Getting the tones was what I found difficult and took me years. I still do not know if I am doing it well as there are not many trained in the kinetics of violin playing enough to correct me. Also getting a good violin bow strings and rosin is very important.
I am not sure how the production Helmholtz motion would modify, or be required for, each of the style mentioned.
