glossary:
Chant, chanting: Chant is often used interchangeably with the Sanskrit word mantra; chanting is also used loosely to indicate either the repetition of a mantra (japa) or the singing of devotional songs (kirtana). 

Mantra: Literally an "instrument (tra) of thought (man)," defined variously in English as a prayer, hymn or song of praise, sacred formula, incantation, or charm. 
A mantra may be meaningful or unintelligible, and may consist of a single letter, a word, or a complete sentence. 

Japa: Literally "muttering, whispering," usually in reference to the repetition of mantras. 

Kirtana (Often referred to as "kirtan;" also called bhajana, "worshipping"): Kirtan is one of the practices of devotional yoga (bhakti-yoga) and consists of singing songs in praise of the deity, usually accompanied by drums and other musical instruments.
Literally translated as "mentioning, repeating, saying," usually translated as "chanting." 

Invocation: A mantra-like prayer usually spoken at the beginning of a ritual or formal practice session to solemnize the occasion. One of the most famous invocations is that to Patanjali, which begins (translation by B.K.S. Iyengar): "Let us bow before the noblest of sages, Patanjali"
