In this first video I show you two didgeridoos, the first one made of wood (chestnut) and the other one made with fibreglass and epoxy.
The wooden one was curved with chisel using the longitudinal cut or "sandwich method". Then, after some years I decided to make an exact replica of it. To do so I calculated the internal volume filling the air column with water. every 20ml of water I measured how much the level increased. After that I put the details in an excel file and I calculated mor than 80 sections along the whole lenght.
The results were used to create a mould for glassfibre.
I obtained a new didge with the same lenght, and same diameters of the air column. They are F tuned, with the first toot in F.
To compare the both sound use the timebar to switch in two points were the two didges are played in the same way.
PAY ATTENTION: I think many of you thought that the material should have a bigger influence on the colour tone. By the way, doing the same experiment in a laboratory I could obtain a closer result.
Infact, during the didgeridoo measurements and manufacturing I certainly made small mistakes due the "homemade" method. Beside, small differences of the position between the didge an the microphone cause a bit different "equlizzation".
THEN: probably some of you expected a bigger difference between the two instruments. some of you already experimented bigger differences between different materials. If you think so, probably you were comparing two didges with different material but olso different shape or different tuning.
for more information, questions and feedback, do not hesitate to drop me a mail.
Thank you for watching.
