12 forum posts | A CBA (Chromatic Button Accordion*) has got buttons on the treble side (unlike a piano accordion that has piano keys). Historically, the buttons have been arranged in 3 rows, with several layouts. B system, aka Do3 (B note in the first (outer) row), C System, with C in the first row (aka Do1). There are other, region - specific systems, like Do2 in parts of Belgium and Finnish C system. Since 3 rows are very hard to play, some clever guy decided to add 2 more rows to the keyboard, so that row 4 doubles row 1, and row 5 doubles row 2. This has made the C system easier and has revolutionised the B system, making it a lot more user-friendly than it used to be. https://en.wikipedia.org/wiki/Chromatic_button_accordion In essence, C system is typically associated with French musette, while B system with Eastern European music. Unless you are in Belgium or Netherlands, where B system is associated with musette music. Or in Germany, where B and C have existed side-by-side regardless of what music you were playing.
I hope this has cleared things up for you - the accordion is really, very straightforward. Until you open it up and see over 2,000 moving parts that all need to be set up to work perfectly.
*Do not confuse it with the British Chromatic Button accordion, which looks exactly the same, but is, in fact, a hybrid between a bisonoric 3-row melodeon and accordion-style Stradella bass, and is therefore not a chromatic button accordion, despite the name. |

12 forum posts | Kiwi Bloke - I've got a couple videos by a Russian melodeon maker on how to make reeds with just hand tools, the traditional way. And I've got some official measurements from a mid 2000s Tula bayan (including the bayan bass monsters!). Happy to share - just in case you're interested in trying your hand at it. One week down the line I've made half a dozen sample reed tongues, including rough tuning, cut a few slots in a solid plank (freehand! I've been told that if I can't do this job freehand, then I don't know how to use a file, so I should learn it first, before I start using jigs to speed up the process), and fitted a reed to to a slot, much better than a soviet factory. Albeit, I still have quite a bit to go before I can match the Italian master craftsmen haha. All that with just a couple regular files. I now need to make some safety files for the job, which might be a bit of a challenge. I am yet to discover the dark art of using solid rivets, but overall, I'm quite happy, given that I've got close to zero metalworking experience. |
