One of the most difficult beats to find is a beat without bass. Most musical styles incorporate some type of bass into the music because of the properties that the bass brings to the songs. Because of this, there are few providers of music downloads that have a beat without bass available.
The best way for a person to attempt to find a beat without bass is to do an internet search for all of the websites that claim to have a beat without bass available. This will give the person a starting point from which to review different types of beats and try to find the one that is right for them. In most cases, these websites will allow the person to listen to the beat before downloading it to make sure that the song they are downloading is the one that they want.
If the person is not having any luck finding a beat without bass that they like on the online websites, then their best choice may be to find a beat and take the bass out of it themselves. There are a number of different music creation programs that will allow the artist to control the amount of bass in a song and it may be possible to take the bass out of a song completely. Then a new bass track can be laid over the existing music to create a more unique sound that is signature to the artist that created it.
