There are a plethora of tones on a two headed bongo.

Like the bodaron the skin head can be tightened or dampened with an opposing hand.

The acoustic play is also varied the percussion point on various parts officiels the head...finger-tips, or finger or thumb aides....both stacotto or lumbratto. The "rest note" can give à profound emphasis.

Sincerelly,

Like any instrument it is best appreciated when in the hands of a master.
