The techniques applied to achieve this differs from musician to musician, some preferring to cut up and rearrange the breaks, while others merely distort and loop breaks or apply various effects such as delay and chorus to alter the break's timbre. Melodically, there is nothing that defines breakcore. Classic rave sounds such as acid bass lines, Hoovers and Reese bass are common, but breakcore is mostly known for sampling sounds from all over the musical spectrum to accommodate the frantic and fast-paced nature of the rhythm section. Around the turn of the century, more and more breakcore musicians began employing traditional synthesis techniques to compose elaborate melodies and harmonies. There are a growing number of musicians who make use of recorded live instrumentation in their music, such as Istari Lasterfahrer, Hecate, Benn Jordan, Ruby My Dear, Qüatros, Venetian Snares, and Igorrr. According to Simon Reynolds of "The New York Times", "purveyed by artists like DJ/Rupture and Teamshadetek, the [breakcore] music combines rumbling bass lines, fidgety beats and grainy ragga vocals to create a home-listening surrogate for the "bashment" vibe of a Jamaican sound system party. Others within the breakcore genre, like Knifehandchop, Kid 606 and Soundmurderer, hark back to rave's own early days, their music evoking the rowdy fervor of a time when huge crowds flailed their limbs to a barrage of abstract noise and convulsive rhythm. It's a poignant aural mirage of a time when techno music was made for the popular vanguard rather than a connoisseurial elite, as it is today." One of the most controversial issues in breakcore is that of the mere existence of the genre. Because it pulls liberally from other musical genres, there is not a consensus on what is and what is not breakcore, or even over the usefulness of the term itself. Raggacore is a style of music derived from ragga jungle that somewhat predates breakcore, characterized by ragga and dancehall rhythms and vocals. Its roots can arguably be traced back to jungle producer Remarc, who was one of the first producers to mix ragga and dancehall vocals with chaotic and intricately rearranged break beats. While only a few producers primarily work in the style, it still has a sizable following among breakcore fans. Notable examples of this style include Aaron Spectre, Bong-Ra, Cardopusher, Enduser, FFF, LFO Demon, Renard Queenston, Lemon Drizlay Crew, Ruby my Dear, Istari Lasterfahrer, Shitmat, Venetian Snares, and Stivs from the Life4Land crew.
