The “Sellinger’s Round” is more stirring. Its theme is in a swinging 6/8 rhythm, running easily through the harmonies of the tonic, the super-dominant and the sub-dominant. It strikes one like an old legend, as in the first part of Chopin’s Ballade in F major, of which this piece is a prototype. The first variation retains the rhythm and only breaks the harmonies. Its gentle fugalisation is more distinctly marked in the third variation, which at the conclusion adopts running semiquavers, after Bird’s favourite manner, anticipating at the conclusion of the one variation the motive of the next. The semiquavers go up and down in thirds, or are interwoven by both hands, while melody and accompaniment continue their dotted 6/8, in a fashion reminding us of Schumann. In the later variations the quaver movement is again taken up, but more florid and more varied with runs which pursue each other in canon. This piece, perhaps the first perfect clavier-piece on record, which had left its time far behind, was written in 1580. Alongside of William Bird stands Dr John Bull (1563-1628). These two represent the two types which run through the whole history of the clavier. Bird, the more intimate, delicate, spiritual intellect; Bull, the untamed genius, the flashing executant, the restless madcap, the rougher artist. It is noticeable how these two types stand thus together on the very threshold of the clavier-art. John Bull, at nineteen, became organist of Hereford Cathedral, and at twenty-two a member of the Royal Chapel. In the following year he becomes Bachelor of Music of Oxford, three years later Doctor of Music of both Oxford and Cambridge. When, in 1596, Sir Thomas Gresham founded his College in London, he was made Professor in Music, and that without (as the statute demanded) lecturing in Latin. But he held this post no more than five years. We find him, “on grounds of health,” travelling in foreign countries. His playing created the greatest enthusiasm. The French, the Spanish, and the Austrian courts were in a furore. Like all later executants, he is the subject of myths. There is an anecdote that a kapellmeister of St Omer showed him, as an extraordinary curiosity, a piece in forty parts.[26] Bull, nothing daunted, added another forty parts to it. The kapellmeister stares, and takes him for the devil himself. After an absence of six years he returned to England, where, like his satanic prototype, he resists all authority. He resigned all academic positions, threw up his post in the Royal Chapel, and in 1613 again set out, without permission, for the Continent. Four years later he emerges as organist of Notre Dame in Antwerp, where he died in 1628. [Illustration: John Bull, at the age of 26, after Caldwall’s engraving in Hawkins.]
