The gandingan a kayo (translated means, âÂÂwooden gandingan,â or âÂÂgandingan made of woodâÂÂ) is a Philippine xylophone and considered the wooden version of the real gandingan. This instrument is a relatively new instrument coming of age due to the increasing popularity of the âÂÂwooden kulintang ensembleâÂÂ. Unlike the original gandingan, the gandingan a kayo cannot be used for long-distance communication.
