to hearing melodies with what he calls a "bass" (an accompaniment founded on chords), and in the commonest music-hall songs the familiar harmonies are the results of centuries of experiment among the ecclesiastical fathers of modern music. It is difficult for us to understand that there was a time when harmony was unknown to musicians, but such is the case; and the f

lled Organum or Diaphony, attributed to Hucbald, a Benedictine monk of St. Armand, in Flanders, near the close of the tenth century. Hucbald appears to have studied Pythagoras's musical system, in which intervals between notes were measured according to the laws of acoustics by the number of vibrations made by each note in a second. Hucbald, finding that certain intervals had a mathematical ratio, decided that they must make concords, and he founded his system of harmony on that theory. He used the intervals of the fourth, the fifth, and the octave. The fourth is the fourth note of the major scale in ascending, the fifth the fifth note, and the octave the eighth, or

rm of harmony in which the lowest note always remained the same. This was what we now call a "drone bass," such as is heard in the bagpipe, and it was certainly more flexible than the other kind because it admitted of the use of other intervals than the fourth and fifth. But the idea of writing in more than one part, once having appeared in music, developed itself gradually. All the earliest harmonic combinations sound ugly to our ears because of the di

ight because it gave them fine opportunities for the display of their voices and of their musical skill. In some parts of France and the Netherlands this practice became a sort of mania. The voice which carried the chant was called the tenor, from the Latin teneo, "I hold." The other voice added an ornamental part above the chant, and as there was no measure in music, the two parts seldom came out together at the end. As long as the voices had moved in parallel fourths o

p or down, and of the number of notes which it was to pass. In Hucbald's day a series of horizontal lines, like our musical staff (but containing many more lines) was used. The names of the notes were written opposite the ends of the spaces between the lines, and then each syllable of the text was written in t

h century both lines were used at the same time, and the certainty of the meaning of the Neumes became greater. Afterward Guido, of Arezzo, a famous teacher and theorist, who died in 1050, added two more lines, and thus came into existence a four-line staff. The character of the Neumes themselves had undergone many alterations, until, in Guido's time, they

two-syllable feet; triple time to one of three-syllable feet. A polka is in dual time; a waltz, in triple time. Franco first explained these points, and insisted that triple ought to be used in church music for the na?ve reason that its three beats in one bar made it resemble the perfection of the Holy Trinity, three persons in one God. He made many improvements in harmony, among others recognizing the third, already described, as a concord, though not a perfect one. Another important feature of Franco's teaching was his advocacy of contrary motion of parts. The manner of writing practised by Hucbald prescribed what is called parallel motion; that is, the melody of the cantus firmus

odious in itself. When the early composers began to write in more than two parts, they still preferred the style in which every part was a melody in itself. In our modern music the parts which constitute the harmonic accompaniment of a melody are not necessarily melodious in themselves, as any one can easily see who listens to the accompaniment of a popular song. The early church composers knew nothing about that kind of writing. They did not have instrumental accompaniment at all. Even after the organ began to be used, it simply pla
