Logo and imagery Despite the band being forced to change their name, Dream Theater adopted a custom logo (known as the Majesty symbol) and wordmark which has appeared on the vast majority of their promotional material and on the front cover of every Dream Theater studio album. The Majesty symbol is derived from Mary, Queen of Scots' mark, which was re-worked by Charlie Dominici for use on the album artwork for When Dream and Day Unite. In September 2010, a fan of Dream Theater discovered that all of the letters of "DOMINICI" fit together perfectly into the Majesty symbol. When Charlie discovered this, he laughed and mentioned that "it only took them 25 years to figure out the 'Dominici Code!'" This has earlier also been discovered as shown on the comment section of DTFAQ and in the DTNorway Podcast Episode 2 from 2008, with Charlie Dominici. Musical style AllMusic's Stephen Thomas Erlewine described Dream Theater's music as a "dense blend of progressive rock and post-Halen metal". The band is well noted for being one of the early progenitors of the progressive metal genre, and they are considered a member of the so-called "big three" of the genre, along with Queensrÿche and Fates Warning. The original members, Mike Portnoy, John Petrucci and John Myung, have strong influences from progressive rock bands such as Rush, Yes, and Pink Floyd, heavy metal bands such as Iron Maiden and Judas Priest, various speed metal bands, and even the glam metal of the day. This synthesis created a unique metal that was not traditional of the day: it had distorted guitars and fast riffing, but the music focused more on technical proficiency and precise execution than on heavy metal riffs. The band's music has focused on three main elements: metal, melody, and progressive roots. In the liner notes for the 2008 Greatest Hit compilation, Mike Portnoy cited artists such as Peter Gabriel, U2, and Journey as inspirations for Dream Theater's softer songs. Dream Theater's music has also been described as art rock. Dream Theater's 2003 album
