The music in Tanks! is deceptively simple. You may have noticed that in the higher levels, when powerful tanks such as the white tanks are destroyed, the background music immediately becomes less complex, less rich. This is because certain types of tanks come accompanied by their own musical instruments!
This is first heard in Mission 8, where yellow tanks are introduced along with a new bass drum beat. The bass of the music is much deeper when yellow tanks are present. Once all yelow tanks are destroyed in a mission, the bass drum component of the music ceases.
The most obvious tank-specific instrument is that that comes with the white tanks. Below is a complete list (special thanks to U.E. for providing this info):
Tank Instrument
Brown Snare drum & flute
Grey Triangles
Teal Tympani
Yellow Bass drum
Red Complex Tympani
Green Bells/Gong
Purple Tuba
White Trumpet & Saxophone
Black Cymbals

I think i found out what black “Features”…
I think Bells are much louder than the other instruments, so if you destroy
a black tank and only a white tank is left, you shouldn’t
be able to hear bells.
Yeah… i noticed that too…
if teal is timpani and cymbals,
then what is Black? that’s what is really puzzling.
Seem like it simply has everything.
Also, it seems green is Bells & Trumpet (in addition to everything before). But in mission 17 there is tympani too, but only in the beginning…. I’m gonna need to devote a lotta time into this to dissect it…
I listened to the game more and it seems the musical arrangements are more complex than simply tank-based. Here are some observations:
It seems Grey is Snare drum, flute, and triangle.
Tympani is present until only 2 enemy tanks remain except teals have their own tympani.
Teal – all of the above plus tympani and Cymbal.
Tympani is somewhat unique in that its volume is dependent on the number and mix of the enemy tanks present. Hmmm…
More to come when I have time to work on this.
I’ll listen closely to the music, just so
the info. isn’t wrong.
oh, and you’re welcome!
