Some ringtones have several different sounds, such as a guitar, bass, or synthesizer.

Custom tonos de llamada for mobile phones first became popular in Finland in 1998, when a Finnish telecoms researcher named Vesa-Matti Paananen created a program called Harmonium that allowed users to create their own ringtones. It was later adopted by other mobile operators, and in 2004, ringtones became a $4 billion industry worldwide.

Finding a ringtone can be difficult, but there are plenty of apps to help you find one you like. Some of these apps are free to download, while others offer an ad-free version that you can upgrade to.

The easiest way to find a ringtone is to go to the Google Play Store or App Store on your Android or iPhone. There you can find a wide variety of ringtones for just about any topic, from today's hits to Harry Potter ringtones to military ringtones.

There are also a few ways to create your own ringtones for your phone, including making a song a ringtone, setting it as your ringtone for various contacts, or trimming a song to tweak it. It's not hard to do, and it can be a great way to make your phone unique.
