Teachers assumed that students will learn words incidentally, and thus pay no or little attention to the teaching of vocabulary(Zimmerman,1997). Some teachers are not confident and familiar with the best practice in vocabulary instruction and thereby don't know where to begin (Berne &Blachowicz,2008). Vocabulary is very essential in learning second language as Wilkins (1972) puts "without grammar very little can be conveyed, without vocabulary nothing can be conveyed" (pp 111_112). With these in mind, Georgi Lozanov, a Bulgarian psychologist developed suggestopedia as a method of teaching to memorized words as doubled the conventional method with the use of music. In this text, suggestopedia as a method and how its improve the learning of vocabulary have been discussed with an experiment using classical music.
