Solfeggio (It) or Solfege,
is a technique for ear training. It is a method of assigning a syllable to every pitch/degree of a scale using the syllables

Solfege was created in the 10th Century by Guido d' Arezzo to help monks to easily learn the chants for the mass. Solfege is a great tool for developing Relative Pitch. It helps to improve sight reading skills -
not only in terms of singing but also on a music instrument.
