Telolet is the term used to describe the usual, distinctive sound of a horn heard from the tourist buses in Indonesia. This horn sound became popular in 2016 when several children in Indonesia recorded the sound of the bus horn and shared it on social media. The recording later went viral and many people participated in imitating the telolet horn with various variations.
This telolet phenomenon had become a trend among electronic music fans (EDM) in various parts of the world, including in Indonesia. Some DJs and electronic music producers incorporate the sound of telolet horns into their music, creating a musical genre known as "telolet" or "telolet trance".
However, it is important to note that trends and virality may change over time.
