Dirty tones
Dirty tones ( English dirty, dirty tones ) originate in the Afro-American music . They were an important feature in African American singing and were used by slaves in their "work songs". In addition, these tones influenced the development of blues and jazz .
Dirty tones were created by squeezing and pressing the voice and were used to increase expression. Since the tones generated in this way sounded unclean and not pure, they were also referred to as " blue notes ".
In addition to the voice, dirty tones were also created with instruments. Various aids were used for this, such as B. dampers for trumpets and trombones or in rock music distortion and wah-wah pedals for guitars .
Dirty tones were first used by musicians in New Orleans jazz at the end of the 19th century. The musicians deliberately intoned uncleanly or played a note a little beside the right one in order to express their individuality .
