  1. https://www.sheetmusicplus.com/title/playing-with-colour-for-violin-book-3-sheet-music/20433105 Don't know if color coded notes would help but may be worth trying. "A carefully correlated blend of colored and traditional note reading, as used in Sharon Goodey's Playing with Colour for Piano, means reading is acquired throughout volumes 1, 2, and 3, resulting in complete comprehension of standard notation by the end of Book 3" Assessment by paediatric speech pathologist or occupational therapist may define the problem more precisely.
  2. https://www.ebay.com/itm/Special-4-4-Violin-baroque-model-European-maple-back-old-spruce-top-hand-carved/233559848798 This is advertised as a "baroque model". Is there a historical reference for connecting the tailpiece and fingerboard?
  3. Thank you. Yes, have tried the SAS and various centre mounted tall chinrests. Currently he likes this one the best.
  4. We are still dealing with this issue. (violin)(now 15 yrs old) Our latest trial is one of these : https://www.ebay.com/itm/CUSTOM-MADE-EXTRA-HIGH-VIOLIN-CHIN-REST/401511301172 combined with an (unfortunately expensive) Korfker shoulder rest with ergo pack. https://www.pirastro-shoulderrests.com/ This is the best combination for him so far.

  6. There are various replacement slides such as: https://www.ebay.com/itm/Fix-A-Zipper-6-pack-Zip-Rescue-Instant-Repair-Kit-Replacement-Tool-Kit/192530261805 https://www.ebay.com/itm/3-Sizes-TV-6Pcs-Fix-A-Zipper-Slider-Instant-Zipper-Repair-Kit-Replacement-Zipper/162149848450 https://www.ebay.com/itm/10x-Metal-ZIP-SLIDERS-Replacement-FOR-No-5-CONTINUOUS-ZIPS-ZIPPER-FASTENINGS-DIY/142424082369 Need to free one end of the plastic zipper and thread the new slide on. I haven't tried the slide with the hinge.
  7. Or the whole back? From the Yitamusic catalogue. http://www.yitamusic.com/upload/violincatalog09.pdf Bamboo Back Violin Unique bamboo back violin. MV5308 4/4
  8. All of his strings wear quicker but especially the A. Sadly, none of my children wipe their strings. However, better to have to replace strings than have long string life due to lack of practise. The example was not meant as a problem, more to make the point that (as Don said), the A string may be less durable, but also that the chemical characteristics of the player may also be a contributing factor.
  9. One of my children needs his A string replacing more frequently than the other children. I wonder if it is due to corrosion produced by his sweat acting on the aluminium. Apparently the corrosivity of sweat depends on the amount of sweat as well as the chloride content. I wonder if the aluminium is more susceptible than the other materials on the strings. https://oem.bmj.com/content/oemed/14/3/191.full.pdf "Results Corrosion by Different Individuals.-Eight male subjects selected at random for preliminary experiments were asked to wear a rubber glove into each of which was inserted a small cylinder of degreased, polished mild steel. After one and a half hours, four of the subjects were found to have corroded the metal heavily and in addition had rust-stained hands, two produced slight tarnishing and two had a negligible effect. It appears that some individuals may handle degreased metal without having any effect while others produce heavy accumulations of rust."
  10. There was some discussion in this thread, page three onwards.
  11. Apparently it has recently been particularly hot in parts of China and I suspect that this is not an uncommon problem as the parcels can get hot while in the post.
  12. With a Romberg fingerboard (bevel under the C string) do you measure the height of the C from the minimum distance to the fingerboard or vertical to the fingerboard or at 90 degrees to the bevel? On rounded fingerboards do you measure vertical to the fingerboard or at 90 degrees to the tangent?
  13. A bit off topic, but for your interest here is a comparison of some Rosewood Knilling Perfection pegs on my son's Collin Mezin compared with one of the original pegs. While I agree that if the historical / antique aspects are of importance it doesn't make sense to use them, for us in the wet tropics they make life a lot easier as they are unaffected by humidity and temperature changes. Just a pity that the shaft looks so synthetic compared to the head (which is wooden.)
  14. Are they Knilling Perfection Pegs?
