parts, some of the suites, several gavottes, modernized from his violin and chamber music, and a very few of his other pieces for the clavier, are habitually played. It would be unjust to close the account of this great artist without mentioning what we might call the prophetic element in his works. The great bulk of Bach's compositions are in two forms, the Prelude and the Fugue. The fugue came to perfection in his hands. It was an application of the Netherlandish art of canonic imitation, combined with modern tonality. In a fugue the first voice gives the subject in the tonic, the second voice answers in the dominant, the third voice comes again in the tonic, and the fourth voice, if there be one, again in the dominant. Then ensues a digression into some key upon what theorists call the dominant side, when one or two voices give out the subject and answer it again, always in the tonic and dominant of the new key. Then more or less modulating matter, thematically developed out of some leading motive of the subject, and again the principal material of the theme, with one or more answers. The final close is preceded by a more or less elaborate pedal point upon the dominant of the principal key, after which the subject comes in. With very few exceptions the fugues of Bach are in modern tonality, the major key or the modern minor, with their usual relatives. The prelude is a less closely organized composition. Sometimes it is purely harmonic in its interest, like the first of the "Well Tempered Clavier." At other times it is highly melodic, like the preludes in C sharp major and minor of the first book of the Clavier, and, as a rule, the prelude either treats its motives in a somewhat lyric manner or dispenses with the melodic material altogether. Thus the prelude and fugue mutually complete each other. But it is a great mistake to regard Bach as a writer of fugues alone. He was also very free in fantasies, and one of his pianoforte works, concerning the origin of which nothing whatever is known, the "Chromatic Fantasia and Fugue," is one of the four or five greatest compositions that exist for this instrument. The remarkable thing about this fantasia is the freedom of its treatment and the facility with which it lends itself to virtuoso handling, as distinguished from the rather limited treatment of the piano usual in Bach's works. The second part of the fantasia is occupied by a succession of recitatives of an extremely graphic and poetic character. Melodically and harmonically these recitatives are thoroughly modern and dramatic, the latter element being very forcibly represented by the succession of diminished sevenths on which the phrases of the recitative end. The fugue following is long, highly diversified and extremely climactic in its interest. In other parts of his work Bach has left fantasies of a more descriptive character. He has, for instance, a hunting scene with various incidents of a
