SECTION VI.— TIME AND ITS DIVISIONS. 



The Bae, made thus, iniT^i: divides a 

 musical composition into T~~" equal por- 

 tions of time. 



Time is divided into two sorts — common 

 and triple ; each of which is either simple 

 or COMPOUND ; and the character, or sign 

 which denotes it, is placed at the beginning 

 of every composition, after the clef.
