15 Feb of this year my Concertina was deliverd on my doorstep.
It is a Wren 2 Anglo C/G Concertina by McNeela. A affordable good instrument.
Features
30 button Anglo Concertina in the key of C/G
Fully chromatic
Measures 6.3″ across the flats (16cm)
8 fold bellows
Steel reeds
Loud, crisp tone
Durable black buttons
Wheatstone/Lachenal layout
Excellent response
Easy to play
Lightweight concertina – easy to handle for all ages
Traditional size – unlike other bulky beginner concertinas
Softer, more comfortable, adjustable hand-straps – suitable for both children and adults
Finished with improved stylish gloss exposed-grain wood
Comes with a complimentary Concertina Padded Hard Case
The word concertina refers to a family of hand-held bellows-driven free reed instruments constructed according to various systems, which differ in terms of keyboard layout, and whether individual buttons (keys) produce the same (unisonoric) or different (bisonoric) notes with changes in the direction of air pressure. It is weird playing two notes with the same button, but i gives you a broader tonal range. Some notes are double, one on the pull action and one on the push action. When playing for a while it is possible to switch between those two to be able to play faster. Because you can use the same pull or push as you already where playing, or the button is close by the one you already play.
A little diagram i drew myself using inkscape to learn the buttons i needed. (Blanks also have notes)
So i had a little problem with the pull motion of the right hand A’ B’. I didn’t want to send my Concertina back (Still has garantee, i know) But sending it back to Ireland will take a while and has postal costs. (I’ve fixed my Accordeon also, so why not try to fix it myself?) (… aaand i was curious of the insides )
I had to look at the inner workings for a minute, and finding the right reed. The middle picture above shows a white plastic strip, one of them was stuck. Moving it a little and carefully bending it, got it free and moveable again.
On with the lessons from Caitlin Nic Gabhann again! https://www.youtube.com/watch?v=Z3tPzc6kKM0
2023 Repair:
One of the reeds fell off! It was not glued properly. A 5 minute fix!
Put the box flat on the table to switch off. When you put it on one side, it will controll your lights brightness. 20,40,60,80 and 100%, just by rotating and putting it down on its sides.

Nice to have’s : Arduino-sleep mode, wakeup with a movement sensor.
