▁ ▁There ▁are ▁various ▁additional ▁rules ▁which ▁apply ▁occasionally : ▁ ▁Some ▁ch ants ▁have ▁more ▁complicated ▁rh yth ms ▁than ▁the ▁example ▁above , ▁generally ▁in ▁the ▁form ▁of ▁a ▁d otted ▁minim ▁and ▁a ▁c rot ch et ▁( in ▁any ▁bar ▁except ▁the ▁last ▁of ▁a ▁quarter ) ▁or ▁of ▁two ▁c rot ch ets ▁taking ▁the ▁place ▁of ▁a ▁minim . ▁ ▁When ▁a ▁minim ▁in ▁an ▁internal ▁bar ▁( i . e . ▁not ▁the ▁first ▁or ▁last ▁bar ▁of ▁a ▁quarter ) ▁is ▁replaced ▁by ▁two ▁c rot ch ets , ▁one ▁of ▁two ▁things ▁happens . ▁If ▁there ▁is ▁only ▁one ▁sy ll able , ▁both ▁notes ▁are ▁s ung ▁to ▁it ▁in ▁quick ▁succession . ▁If ▁there ▁are ▁two ▁( or ▁occasionally ▁more ) ▁sy ll ables , ▁they ▁are ▁split ▁as ▁appropriate ▁to ▁smooth ly ▁match ▁the ▁rh ythm ▁of ▁the ▁words ▁to ▁the ▁two ▁notes . ▁ ▁When ▁an ▁internal ▁bar ▁has ▁a ▁d otted ▁rh ythm , ▁it ▁is ▁to ▁be ▁s ung ▁as ▁above , ▁except ing ▁that ▁the ▁c rot ch et ▁can ▁be ▁omitted ▁from ▁the ▁music ▁if ▁the ▁natural ▁rh ythm ▁of ▁the ▁words ▁and ▁the ▁sentiment ▁of ▁the ▁words ▁indicate ▁that ▁it ▁is ▁appropriate ▁to ▁do ▁so . ▁ ▁When ▁the ▁first ▁bar ▁of ▁a ▁quarter ▁has ▁a ▁d otted ▁minim ▁and ▁a ▁c rot ch et , ▁all ▁sy ll ables ▁except ▁the ▁last ▁are ▁s ung ▁to ▁the ▁note ▁of ▁the ▁d otted ▁minim ,
