Of the many creative endeavors, music is probably one of the hardest to learn and practice. And of the well-known musical instruments, the violin is one of the hardest to play. But what if you can play the violin or some semblance of the instrument as easily as you could press down keys on a piano? And what if that produced the unique tonal quality of a violin while still hitting all the right notes perfectly? That’s the kind of musical experience that this DIY synthesizer offers, combining two classical instruments in a single form that might leave you confused with one hand playing the keyboard and the other playing the violin.

Electronic keyboards can try to mimic the sounds of different musical instruments, but they don’t always work. They can’t, for example, reproduce the unique vibrating quality of the violin family, which at the very least would require some physical medium to produce that kind of sound. Conversely, violins are hard to master because you need to also move the bow at a very precise location to hit the right pitch, and that location isn’t marked like on a guitar.
Key-bowed, which is a very creative name, tries to combine the strengths of both the keyboard and the violin with very few of the flaws. It’s actually an idea decades in the making, but it’s finally possible to pull it off thanks to modern technologies and hardware. The synthesizer combines a Roland K-25m keyboard, an Arduino Uno R4 minima controller, and a self-made bowing sensor with a vertical acrylic plate. Of course, the assembly also requires some programming know-how, especially when dealing with sound waves.
Despite the complexity of the build, using the Key-bowed looks pretty simple, at least for the musically inclined. You simply hit the keys with one hand to produce music like on a regular keyboard or piano, and then you use the other hand to move the bow across the acrylic plate as you would with a violin. The vibrations on the plate are detected by the sensor and then transformed into waves that modify the note that’s produced, resulting in a very realistic recreation of a violin sound, with perfect pitch, and without the screeches. You can even pluck the plate and make it sound like you’re really plucking a string.

Key-bowed is definitely a work of genius that makes playing music both fun and enchanting. It still requires you to have some basic music knowledge, of course, but it makes the execution less daunting, especially if you’ve always dreamed of playing the violin. Of course, there are limits to the music you can play, since you’re technically producing notes with only one hand, and the design is made for those who hold the violin bow with their right hand. Nonetheless, it still creates a captivating experience, and hopefully, it can become a commercial product that will let everyone enjoy that experience as well.
