Formation and ''The Space Between'' EP (2011–2012)
Intervals was formed in Toronto, Ontario in 2011 as a creative outlet for guitarist Aaron Marshall after quitting his previous band, "Speak of the Devil". He recorded and programmed all the parts for The Space Between in his home studio, with mixing and mastering by Adam "Nolly" Getgood of Periphery, and released independently on December 20, 2011. Marshall attempted to form a full band including a vocalist, with the intention of turning Intervals into a touring act, but failed to do so.
''In Time'' EP (2012–2013)
With the release of their second EP In Time on October 30, 2012, Marshall was joined by Olly Steele and David Maxim Micic. Sputnik Music gave the EP a 4.0/Excellent rating, suggesting that "if they find a bit more creativity and increase their originality, they have potential to go down in history as one of the best instrumental prog metal bands. As of now, they are still not on the same level as Animals as Leaders." The band released a music video for "Epiphany" on April 25, 2013 via Guitar World promotion and YouTube. Following the success of In Time, the band gained endorsement deals from Ernie Ball Music Man, Pearl Drums, Meinl Cymbals, Toontrack, InTune Guitar Picks, and Gruv Gear. Marshall also released playthroughs and lessons for certain songs from the EP.
''A Voice Within'' (2013–2015)
On September 14, 2013, Intervals announced they would be entering the studio with producer Jordan Valeriote on November 4 to begin tracking their upcoming release. Following the studio, Intervals were scheduled to tour Europe with Protest The Hero, TesseracT, and The Safety Fire. On December 30, it was announced that bassist Mike Semesky would be changing his role in the band and provide vocals on the new album; as a result, the album's bass tracks were handled equally by Marshall and Valeriote. The band released Semesky's vocal debut in the form of new single ‘Ephemeral’ via RevolverMag.com, as well as a revelation that the new album would be titled A Voice Within. Due to the need for Semesky to focus entirely on his vocal performance live, the band hired Henry Selva as their live bassist for their upcoming tours. The band released a second song from the album, "The Escape", on January 23, 2014 and announced that the album would be released on March 4, 2014. On February 26, the band announced that they would be releasing one new song from the album per day until the day of the album's release. The first of these songs was "The Self Surrendered".
Departure, ''The Shape of Colour'', and ''The Way Forward'' (2015–present)
On November 25, 2014, Mike Semesky was announced to have left the band. An instrumental version of A Voice Within was then released on March 3, 2015. On June 23, three months after, Guyader and Sastry announced on Facebook that they would no longer be a part of Intervals. This separation was caused by different expectations about the direction of the band: Marshall then introduced new studio musicians, bassist Cameron McLellan and drummer Travis Orbin, to work on the band's next album. On December 4, 2015, Intervals released The Shape of Colour. On October 24, 2017, Intervals announced The Way Forward, a new album with McLellan returning to bass, and new drummer Nathan Bulla, who had been playing live with the band until the release. Marshall continues to be the only member of the band, despite having returning members for tours and albums.
