Ocarina

I bought one when I went home last time in January, but I've been busy so I didn't really have time to play with it until yesterday. The instruction sheet says that at most 12 sounds can be played with this type of ocarina, from F3~C5 (or it can be shifted, as I don't have absolute sound). The available songs are very limited, for example there is no #C or #F. I didn't notice it when I bought it, but well, it's probably how it works.

Then I played with it for a while, trying out different songs. And I discovered that the available frequency spectrum is actually continuous! One has to cover the holes partially to get the intermediate sounds. To be honest I don't know how exactly it works even though I'm a physics major, but it seems that the frequency is dependent only on the total area that the air can come out from the ocarina. I have to think harder to check this.

Going on to today's sketch. The siting-on-tree one is kind of boring, so I started a new sketch. Now I think of it, the direction of the sword is wrong. It should be rotated 90 degrees given the hand position (if it is western fencing style). But I guess nobody cares about it :p
