The X of it.

Amadindas are traditionally played in groups and feature 15 keys. Akadindas employ anywhere between 10 and 20 keys. Two people can play the ten-key model while four people can play on one 20-key model. The keys on the Akadinda are traditionally a little smaller than the ones found on the Amadinda.

Six players can use wooden sticks to play the Embaire. These are unlike many of the other different types of "X" available. They can measure up to 12 feet in length and feature 21 keys. Balafons consist of between 18 and 21 keys traditionally made out of rosewood. These keys usually get mounted onto frames made out of bamboo.

The Kulintang-a-kayo features eight keys made out of any number of different soft woods. The Gandingan-a-kayo has four keys, as opposed to eight. These "X" are engineered to create similar sounds to a Gandingan, an instrument that consists of a series of hanging gongs.
