3D Printing a Melodica (1) – Why the melodica?

3D Printing a Melodica (1) – Why the melodica?

Why the melodica?

I started practising the melodica seriously a few years ago, when I needed an instrument to play Irish music with, which I could easily take to play at the informal pub sessions. I already played the piano, so the piano accordion was the obvious first choice. But I gave it a go, and there’s something about the bulky size and weight, and that huge sound, which put me off. I was always fond of the melodica, the simplicity of the piano keyboard, only having to play with one hand, and of course there’s always that element of fun. I decided to take it up as if it were a professional instrument, and dedicate some years to seeing what I, and the instrument were capable of achieving.

What’s already out there?

I’ve tried many melodicas over the years, from the cheapest plastic “toys” to the high end Italian made wooden models. Of these, three models have become my favourites – the vintage Clavietta, the Vibrandoneon (MkI) and the Yamaha Pianica. Each one has its pros and cons. The Clavietta looks retro and professional, it’s light and has a beautiful tone. It’s far too quiet though for use with other acoustic instruments. The Vibrandoneon, made of wood, is much louder, and also has a great tone, as it uses very high quality reeds. The downside is the size – it’s awkward and heavy to hold, and takes a lot of breath power to make a sound. Also, beautiful as it is to look at, the wooden case is susceptible to mould, as the melodica gets very wet inside from extended playing.

And the favourite?

The Yamaha Pianica is one of the cheaper melodicas, developed for use in schools in Asia. The reeds are harmonica style, as opposed to the accordion style of the other two, resulting in a “honkier”, less refined tone. It also means the reeds go out of tune quicker, and fail more often. But it has some great pros. Because it’s made of plastic, it doesn’t suffer from mould issues, and it’s very light and easy to hold. It takes little breath to achieve a very loud sound, and the sound does actually have a special character of its own. There’s only one drawback – it looks like a toy. The burgundy 37 key model is borderline, but the 32 key model, prized for its compact design is only available in bright blue or pink!

The challenge!

I wonder wether it’s possible to build a melodica based on the Pianica, perhaps using the same reed plates, but redesigning the keys and casing, to make something beautiful? I believe 3D printing has got to the level now where it’s possible to do this at a relatively low cost. I have some experience of 3D design, but would need some help in developing my skills to the level required to build this beast. A homemade melodica. This has got to be one of the most exciting projects I’ve embarked on for a while!

    Troy, ebay has a professional 36 up for bid. If you are considering the reeds the buy it now is to high for parting it out. But if you can get it at a low cost it would definately be a win win. It has just been serviced so you can here the tone and then take the reeds and see how they work or re sell it.

      Thanks very much for the heads up MM! I think I may wait for one which needs some repair, to get a good price. I agree the ‘buy it now’ price is a bit extreme

    Troy, I took some pictures of the Hohner Pro 36 next to melodicas that you own so you can compare.

      Wow, thanks MM, that’s really good of you, and really useful. Looks like its pretty much a standard melodica size.

    Do you know what the key size of the Hohner Pro is? I wonder if it’s slightly bigger than the Yamaha to accommodate the bigger reeds?

    Good idea MM. I’ve never actually played the vintage Hohner Professional, only heard of its legendary status. This sounds ideal – a small light plastic based instrument with high quality single accordion-style reeds. I’ve already started dismantling a Yamaha P32D, but I think I’ll also look out for the Hohner on Ebay, with a view to taking one of these apart as well, and using those reeds…

      Sorry, I replied to the wrong post above. Here it is again.

      A beautiful Hohner Professional sold on Ebay about two weeks ago for $186 and 49 bidders. It was in near new conditions. I wish I got that one. Lowboy

    Troy, you had a great idea using the reeds of the Clavietta on a plastic melodica, though volume was low you may want to consider staying in that direction and using the reeds of the Hohner Professional. Which are pretty loud and do have a great tone. They do come around on ebay every so often. The mechanics are simple as well. Just a though.
