There is no doubt that music effects our emotions, whether it be positive or negative, to some extent. Music has even been used by healthcare providers to assist with the treatment of diseases and other ailments. Our stress, social, and activity levels is influenced by music of which for some the purpose is to calm us down while for others the songs are meant to increase excitement. In a business setting some stores have used music to influence buying decisions of prospective customers.
Words within a song is one of the primary influencer whether it promotes good behavior, wrong doings, religious beliefs, anger, love, praise, or even just telling a story. Whether it be children grow up listening to nursery rhymes, teenagers listening to the radio, or adults attending concerts we are all stimulated by the lyrics which affects our memories. Everyone has a favorite jingle either because they heard it during a memorable event as well as a least favorite song because it was played during a low time in their life. This might explain why some businesses may choose to feature only instrumental music by less-popular composers in order to reduce the potential of negativity. Another attribute of music that affects us the speed of the song. Songs with a fast beat are more likely to increase excitement and happyness while those with a slow beat in contrast usually results in a calming effect. The speed of a song is measured in beats-per-minute of which some of fastest are well above 1000bpm while the slower are less than 100bpm. There are even some songs without a specified beats-per-minute such as “As Slow as Possible” by John Cage.
There are three sources of music within a virtual world; audio files played by a prim, streaming music configured on the parcel, or the audio syncronized to a video clip. Localized music can be projected from objects in-world which are scripted to play an audio file that has been uploaded to the server. The object typically will either play it on repeat or will play a series of audio files back-to-back segments if the complete piece extends beyond predefined technical limits. Streaming music can configured on a parcel by opening the land settings and copy/pasting the URL to the stream into a designated field. Video clips are configured within the parcel settings in a similar manner as streaming audio with the video itself visible on a specially configured prim in-world. For obvious reasons it is best not to use two or more of these three methods at the same time as it can be confusion for the avatar trying to enjoy it.
