Our brain can be optimized with music. Email what kind of music is best for our brain. I know that I use the drums to create sounds as I pray since in the olden times, drumming is a way by our ancestors to talk or pray to God. And there is this Music Genome Project at Pandora to classify music and find detailed attributes for each.

The Music Genome Project was first conceived by Will Glaser and Tim Westergren in late 1999. In January 2000, they joined forces with Jon Kraft to found Savage Beast Technologies to bring their idea to market.[1] The Music Genome Project is an effort to “capture the essence of music at the most fundamental level” using over 450 attributes to describe songs and a complex mathematical algorithm to organize them. The Music Genome Project is currently made up of 5 sub-genomes: Pop/Rock, Hip-Hop/Electronica, Jazz, World Music, and Classical. Under the direction of Nolan Gasser and a team of musicological experts, the initial attributes were later refined and extended.

A given song is represented by a vector containing values for approximately 450 “genes” (analogous to trait-determining genesfor organisms in the field of genetics). Each gene corresponds to a characteristic of the music, for example, gender of lead vocalistprevalent use of groovelevel of distortion on the electric guitartype of background vocals, etc. Rock and pop songs have 150 genes, rap songs have 350, and jazz songs have approximately 400. Other genres of music, such as world and classical music, have 300–450[2] genes. The system depends on a sufficient number of genes to render useful results. Each gene is assigned a number between 0 and 5, in half-integer increments.[3] The Music Genome Project’s database is built using a methodology that includes the use of precisely defined terminology, a consistent frame of reference, redundant analysis, and ongoing quality control to ensure that data integrity remains reliably high.[2]

Given the vector of one or more songs, a list of other similar songs is constructed using what the company calls its “matching algorithm”. Each song is analyzed by a musician in a process that takes 20 to 30 minutes per song.[4] Ten percent of songs are analyzed by more than one musician to ensure conformity with the in-house standards and statistical reliability.

The Music Genome Project was developed in its entirety by Pandora Media and remains the core technology used to program its online radio stations in response to its users’ desires. Although there was a time when the company licensed this technology for use by others, today they limit its use for just their own users.

Because of licensing restrictions, Pandora is available only to users whose location is reported to be in the USA[5] by Pandora’s geolocation software.[6] Before 31 July 2017 it was also available in New Zealand and Australia, but this service has now ceased.
