II. AN ENGLISH FOLK-SONG.
In Figure V is shown the old English song "Polly Oliver."[4]
FIGURE V.
This is a traditional song handed down without any record of its origin, from generation to generation. Its unknown composer has managed very deftly to make it hang together. A good deal is made, in particular, of the characteristic little motive of three notes which first occurs at the beginning of the third measure.[5] In the very next measure, the fourth, this is "transposed" to a lower position. Going on, we find it coming in again, most effectively, in measure 7, this time transposed upwards; and it occurs again twice at the end of the melody. Thus a certain unity is given to the entire tune. Again, the device of repetition after contrast is well used. After measures 1-9, which state the main idea of the melody, measures 9-13 come in with a pronounced contrast; but this is immediately followed up, in measures 13-17, by a literal repetition of the first four measures, which serves to round out and satisfactorily complete the whole. We thus see illustrated once more the scheme of form which, in the last chapter, we denoted by the letters A-B-A.
This song presents a further element of form by means of which much variety is imparted to music.
