Heretofore we have sung tunes of but one part. A single succession of sounds is called a Melody. When two or more parts move together, they form Harmony. A tune of only two parts is called a Duct. We will now try an exercise of two parts, and to do this well, we must divide our class. The ladies sing one part, the gentlemen the other part. In order to give variety, the ladies may sing, sometimes, the upper part, and sometimes the lower part. The gentlemen singing alternate parts. Another change may be made by giving half the ladies and half the gentlemen the upper part, and the other half the lower, or vice versa. See exercises 16 & 17. The line just before the clefs connecting the two staves together is called a Brace. A Brace may be used to connect two, three, or four staves together.
In performing a piece of music it is often both pleasant and necessary, to pass over portions of time in silence. The time of silence must be measured the same as the time of sound. Characters called rests, corresponding in length with the different notes we use, are employed to indicate the time of silence. In No. 20 we use the Quarter Rest and give it one beat, the same as the note. The rest sometimes occurs in the first, and sometimes in the second part of the measure. We must beat the time with great care and steadiness, so that we may both rest and sing together. It is a good plan to divide the class and let half count and beat the time, while the other half sing; than change and let those who marked the time sing, and those who sung do the counting and beating. It is well at first to count aloud during the rests, afterwards beat without counting.
EXERCISES FOR THE SINGING SCHOOL.
No. 28 introduces two quarter rests in some of the measures.
In No. 33, we introduce the Quadruple measure, having four beats. motions of the hand are, down, left, right, up, or Downward beat, Hither beat, Thither beat, Upward beat. There are two accents in this measure, occurring on. the first and third beats. The one occurring on the first beat is called primary, and that on the third beat, secondary. The first being louder than the second. The after the clef, signifies that four Quarter notes fill the measure. The come to me. 4 No. 29. Half and Quarter notes differently arranged. The accent comes, class should first count four, eight, or twelve Quadruple measures, and beat the as it generally should, with the accented part of the word. Hold the tone steady time while counting. through the half note, and beat the time steady.
