It is hardly necessary to add further examples, as these three give a fairly broad idea of the progressive attempts at a definite form, from about the eleventh to the end of the fourteenth century. During this period there were doubtless no hard and fast rules for tuning. The minstrel adapted the pitch of his instrument according to whim, or the compass of his voice. He danced and sang to his own improvised accompaniments. Thus we hear in 1391 of: “Un nommeé Isembart jouait d’une rubèbe, et, en jouant, un nommé Le Bastard se print à danser,” and again in 1395, “Roussel et Gaygnat preurent à jouer, l’un d’une fluste l’autre d’une rubèbe, et ainsi que les aulcuns dansoient.”[11] The minstrel’s person and attainments were undoubtedly of a genial character, yet with all due deference to his merry ways, and the good service he rendered to poetry and music, one cannot help observing that his dancing and warbling were the means of retarding the development of musical instruments to a certain extent. If you roam the country with your musical equipment upon your back you naturally require something of a portable size. “A fiddle under my cloak?” says the indignant Sir Roger l’Estrange in defending himself against Mr Bagshawe’s insinuations that he frequently solicited private conferences from Oliver Cromwell with a fiddle under his cloak; “Truly my fiddle is a bass-viol, and that’s somewhat a troublesome instrument under a cloak.” The minstrel of the Middle Ages was certainly of the same opinion, and was careful that his fiddle should not assume alarming proportions. He was content so long as he could carry it about with ease like “Gervais de Nevers” who: --“donned a garment old And round his neck a viol hung For cunningly he played and sung.” Another obstacle to the progress of stringed instruments was placed in their way by the early contrapuntists who expended their genius entirely upon vocal music. Thus it was that no one appeared to realise that a resonant bass-viol, answering to the pitch of the bass voice, could be constructed by enlarging the rebecs and embryo viols then in use. Not until the middle of the fifteenth century did anything of the sort appear, and when it did, it came at the imperative call of the part-songs then coming into vogue. The singers of these compositions demanded to be kept in tune just as much as the warblers of sweet melodies had required, and it was the desire to do this to the best advantage that led eventually to the construction of complete sets of stringed instruments played with a bow and answering in pitch to the treble, alto, tenor, and bass voices.
