This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1872 edition. Excerpt: ...the two sounds are of different pitch; c % to d 9 is an interval, because differently represented on the staff, Such intervals as this latter, are sometimes termed paper intervals, because they only exhibit a difference on paper. An interval is measured by the number of degrees it occupies on the staff. Thus c to d is a second; c to e, a third; c to f, a fourth; &c. These names, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, may be termed the principal names; but, since d, occupying the second degree of the staff, may appear as dh, dj, or dP, and every sound on the other degrees of the staff is also subject to similar modification, it is evident that other--accessory--names must be employed to represent the kind of 2nd, 3rd, 4th, &c. The following are the accessory names used, viz., Major, Minor, Perfect, Imperfect or Diminished, and Augmented or Extreme. They are distinguished by the greater or less number of semitones they contain. 1. Major is applied to 2nds, 3rds, 6ths, and 7ths. In all major diatonic scales the intervals--reckoning from the tonic to each note in the series--are always either major or perfect: --e. g., in the scale of c, c to d is a major 2nd; c to e, a major 3rd; c to f, a perfect 4th; c to g, a perfect 5th; c to a, a major 6th; c to b, a major 7th; c to c, a perfect octave. 2. Minor is applied to 2nds, 3rds, 6ths, and 7ths also, and is the term for an interval containing one semitone less than the major of that name: --e.g., c to e 1 is a minor 3rd; c to a?, a minor 6th. 3. Perfect is applied to 4ths, 5ths, and 8ths or octaves, which are so termed because they cannot be increased or lessened by sharps or flats, without changing them from concords into discords. 4. Imperfect or Diminsned. Imperfect is applied to 4ths and...
