(Dee - A so bam) Dee originally wrote this word as Asobama - but he dropped the final a in hi phonetic note and in the 48 Claves. So the word is only three syllables long. The initial A stands alone. The o should take its long sound.
(Dee - a-sóbam) See the 48 Claves. Here, Dee placed an accent over the second syllable.
