The real Blue Notes are between Eb and E, Bb and B or Gb and G. With string instruments the effect is achieved by for example playing an Eb and at same time bending the string. For wind instruments the Blue Notes are played with the so called „lipping down“ — lip technique, by playing for example an E and then altering the tone downwards.
