Reading Music

	Staff is constituted of five parallel lines. Bars delimit measures. The Sol key indicates where is the Sol note by the point of its buckle . The 4 / 4 sign means that a measure contains 4 duration notes 1 / 4 who is a quarter . We can add lines over or under staff ( as for the Do note ) .
To fill a measure it is necessary to have a note called whole or two notes called half or four notes called quarter or eight notes called eight . Of course duration can vary provided that the total of times of all notes and possible silences is equal to the duration of a measure .
	To each duration of note corresponds a duration of silence ( rest ) . If a dot is situated after a note we have to play it 1 / 2 time more long . If two notes are linked we play only a duration equal to the two . If three notes are linked with the inscription three ( 3 ) this is a tuplet . These three notes have to be played with a duration corresponding to two notes .
If sharps or flats are situated beside the key that means that these alterations have to be applied on all notes with the same name . The natural sign serves to cancel all preceding sharps or preceding flats . If bars of measures are double and associated with two dots that indicates that it is necessary to repeat measures situated between these bars .
	The drums are symbolized by a simpler manner because there are no notes . Duration between sounds are drawing in the same manner that notes . A lot of current rhythms are played in measures with four time ( 4  / 4 ) . Base for drums : bass drum on time 1 and 3 , snare drum on time 2 and 4 .
