Ancient Chi Transverse Flute Gets 3D Printed Reincarnation

If you had been living the high life near the Marquis Yi of Zeng in 433 BC, you might have been lucky enough to hear a performance on the Chi (篪), a transverse flute that was most likely used for court and ritual music. Unfortunately, in the more likely event that you weren’t, the instrument declined in favor, for reasons not entirely certain, and largely disappeared from music history. However, over the last few decades, there has been a small, but devoted, interest in bringing this instrument back to life.

One person who has shown an interest in this instrument is the musician Cheong Li who decided as part of studying the instrument that he would try to create a 3D printed one. This application of 3D printing technology opens up a world for the study of extinct instruments, as explained by Lee in an interview with 3Dprint.com:

“I’m a musician and a novice to 3D printing. I’m not that capable in woodwork, but 3D printing allows me to draw and design my own instrument easily. One thing I’m particularly interested in is music archaeology. There are quite a lot of ancient instruments that have been forgotten or abandoned in the course of history. It would be very interesting to make them and be able to actually hear what they sound like.”

The Chi is a particularly unique instrument. Unlike the flute, fife, or recorder, the air is introduced into the instrument in the center and the holes for fingering are on either side of the mouthpiece. The ends of the flute are actually closed and the sound is produced as the air is blown into and then escapes from the holes that are used for fingering. Information about the flute is scarce and Lee is having to discover the instrument’s secrets the old fashioned way: trial and error.

The position of the holes doesn’t seem to have much impact on the pitch but rather it is their size that has the greatest effect. The fingering itself is irregular, meaning that rather than playing a scale by lifting successive fingers, each note has a unique fingering configuration. As part of understanding the instrument, Lee has created a fingering chart in an effort to codify the relationships between pitch, frequency, and finger position.

He described the process of designing the instrument in preparation for 3D printing:

“I’ve been using Rhino for Mac. It wasn’t too difficult to draw a simple tube like this. However, the most difficult thing is to determine where I should put the finger holes. I’ve spent some time studying pictures of Chi from various sources and tried to figure out the exact measurements. The tuning is not quite accurate yet and I think I’ll need to rework it.”

He printed his instrument as a single piece with the exception of a final cap for the end which was printed separately and then glued into place. The printing was done via 3D Hubs on a FlashForge Creator Pro and took only a few hours to complete. The instrument Lee printed is created entirely in PLA and the interior dimension is 14.2 cm with an extra centimeter on each end that acts as the wall.

Now that his flute is printed, it seems to have raised more questions than it resolved and Lee plans on diving further into understanding its mysteries.

“There are quite a few questions about this instrument that intrigue me,” Lee notes. “For example, why is the fingering so unpredictable? How does a closed tube sound different from an open tube? To understand these things, I may need to collaborate with a scientist to calculate the physics behind it. It may help to solve a mystery in music history, and if possible, I hope that this instrument can be mass produced and played by more musicians. I’d love to write a tune for it as well!”

This is the third instrument that Lee has created through 3D printing; the first was a Xun, which is an egg-shaped blowing vessel, and the second a sliding whistle. The opportunity to truly understand an instrument that is presented through creating the instrument itself adds a new level of interaction that is open to more and more people through 3D technology. We may never know the way this instrument sounded when it was played 2,000 years ago, but thanks to 3D printing, we can hear it as it has been reincarnated today.

3D Printing’s Musical Journey

Friends, customers, printaholics – lend us your ears and join us along a 3D printed musical adventure!

A recent post which featured one of Malta 3D Printing’s favourite little musical toys – a kazoo – inspired us to continue down this musical vein.

To place things into perspective, the 3D printable instruments of today are split into three categories.

Firstly, we have ‘experimental pieces’, which don’t have a conventional equal outside of the realm of 3D printing. Secondly, there are ‘enhanced instruments’, which improve the qualities of an already existing instrument thanks to 3D printing’s unique capabilities.

3D Printing Will Soon Turn This Design Into Reality

Finally, we have replications of existing instruments, which have no real added benefits compared to the traditional piece.

Pictured above is a prime example of a 3D printable musical piece still in experimental stages.

This unusual trumpet is reminiscent of a modern painter’s masterpiece rather than a practical musical device.  While this aesthetically pleasing instrument is yet to be created, there are others which are already in circulation.

The video below provides a quick explanation about a 3D printed flute. Using the powerful Objet500 Connex, this wind instrument’s 3D model was produced using Rhino.

In a different interview, flute player Seth Hunter emphasized the plastic flute’s acoustic similarities to the traditional metal ones. He also noted the slight misplacement of the keys – but remember – 3D printing encourages technicians to fix any minor errors in the subsequent print.

Created by yet another student from MIT, Amit Zoran was not far away from creating an exact replica, and this was way back in 2011. The traditional flute falls under the ‘existing instrument’ category, but our next pick certainly has its fair share of enhancements.

A laser-cut violin made from plywood, this stringed instrument was created by Ranjit Bhatnagar, a sound art enthusiast.

Its’ bulky wooden outer shell provides a stern contrast to the graceful sounds it can produce. Bhatnagar even took his masterpiece to the streets, inviting different violin players to fiddle away. Check out the videos here!

An ‘Enhanced Instrument’ – 3D Printed Violin

‘Ranjit’ as he is known on Thingiverse, has a personal page chocked full of free designs for different instruments – including an okarina, organ pipe, spiral panpipes and more.

Next up is another piece seeking to replicate an original design, but this one is slightly different. At four feet long, this home-made behemoth requires many printing sessions.

Clearly, this great bass recorder functions well – and the creator has since improved on his original work. The recorer is made up over 48 inches of PVC pipe measuring 1.5″, a few sections made of 2″ and multiple, custom built 3D pieces.

Created by Instructables user ‘sngai’, a quick internet search will reveal that opting to print this object as opposed to purchasing a store-bought one will save players a lot of money.

Who knows what the future holds? PLA pianos, ABS acoustic guitars and printable drum kits may soon become popular. As the number of 3D printed instruments continues to grow, its only a matter of time before musicians hop on the fast-moving bandwagon!
