surely what double-stoppings, chords, and figures were possible on the gamba, and in this respect reveal a remarkable richness in various styles of playing. Opposed to this by its simplicity in a technical point of view is a “Sonata a Cembalo Obligato col Viol da Gamba,” by Handel. Double-stops and chords are altogether omitted. It is true that he has quite another object in view, for Handel treated the gamba not like Schenk, as a solo instrument, but as subsidiary only to carry out a musical idea, thus placing it on a level with the clavier. He chiefly uses also the middle positions of the gamba in the alto key throughout. Otherwise this Sonata,[33] though solid in form, is of small importance, and gives the impression of a composition quickly thrown off for some special occasion. Handel’s great contemporary, Joh. Seb. Bach, treated this instrument, in his three sonatas composed for it and the clavier, in quite another manner. It is true that with rare exceptions he makes no use of the scored and harmonised technique for the gamba; but the artistic and complete mode of working out by which all his instrumental works are more or less distinguished is also peculiar to the gamba sonatas just mentioned, of which the most important are the first in G major and the third in G minor. Charmingly and with characteristic effect did Bach employ the gamba in his Passion Music from the Gospel of St. Matthew and St. John, as well as in some of his Cantatas. One has only to recall the splendid, deeply touching alto aria “It is finished,” in the Passion Music of St. John. Now at the performance of this sublime work the gamba part in the aria referred to is played by the violoncello, which does not quite express the deeply melancholy, pathetic tone that Bach’s music was designed to express. But there is no more appropriate substitute in the modern orchestra for the gamba than the violoncello. One peculiarity of Joh. Seb. Bach is that, with a rare knowledge of art, he made use for his purpose of all the instruments current in his time which adapted themselves in any way to the representation of a special effect. But he further conceived the idea of enriching the choir of instruments by an invention of his own. During his work at Köthen he constructed the “Viola Pomposa,” a stringed instrument of the cello kind, though, like the violin, for the hand, which had five strings tuned to C, G, d, a, ē-- [Illustration] Gerber remarks concerning it: “The limited way in which the violoncello in Bach’s time was handled compelled him, for the quick basses in his works, to the invention of the so-called viola pomposa, which, rather longer and higher than a tenor, had a fifth string, e, in addition to the four lower strings of the violoncello, and was placed on the arm. This convenient instrument enabled the player to execute more easily the high and rapid passages which occurred.”
