TROMP

is evident that the instrument had been introduced from Spain and not from France (where it bore the name of saquebute), as some have assumed from the more frequent use of the word sackbut. The band of musicians in the service of Henry VIII. included ten sackbut players, and under Elizabeth, in 1587, there were six English instrumentalists then enjoyed a certain reputation and were sought for by foreign courts; thus in 1604 Charles III. of Lorraine sought to recruit his sackbut players from English bands.[1] Praetorius[2] classes the trombones in a complete family, the relative tonalities of which were thus composed: 1 Alt-Posaun, 4 Gemeine rechte Posaunen, 2 Quart-Posaunen, 1 Octav-Posaun — eight in all. The Alt-posaun was in D. With the slide closed, it gave the first of the accompanying harmonics: —

The gemeine rechte Posaunen, or ordinary trombones, were Without using the slide they gave the subjoined sounds: —

The Quart-Posaun was made either in E, the fourth below the gemeine rechte Posaun, or in D, the lower fifth. In the latter case it was exactly an octave below the Alt-Posaun. The Octav-Posaun was in A. It was, constructed in two different fashions: either it had a length double that of the ordinary trombone, or the slide was shortened, the length of the column of air being still maintained by the adaptation of a crook. The first system, which was invented by Hans Schreiber four years before the work of Praetorius appeared, gave the instrumentalist a slide by which he could procure in the lower octave all the sounds of the ordinary trombone. The second system, which Praetorius had known for years, was distinguished from the first, not only by modifications affecting the form, but also by a larger bore. Mersenne[3] calls the trombone trompette harmonique, or tuba tractilis. He describes carefully the seven positions and gives the diatonic scale for the first octave, but he does not, like Praetorius, mention the pitch of the trombones in use in his day. He established this fact, however, that it was customary in France, as in Germany, to lower the instrument a fourth below the pitch of the ordinary trombone by means of a tortil, a kind of crook with a double turn that was fitted between the bell and the slide, “in order,” he said, “to make the bass to hautbois concerts.” This system, so simple and rational, might have been expected always to serve for the basis of the technique of the instrument; but from the middle of the 18th century the art of playing the trombone became the object of purely empiric teaching. Owing to the decline in the popularity of the trombone during the 18th century in England, France, Germany and Italy, writers of that period are sometimes at a loss to describe the working and effect of the slide, as were the early 16th-century authors. J. J. Eisel, and after him Jacob Lotter, whose work is a réchauffé of Eisel's, mention four principal positions, “the others not being of much importance.” The lowering of the pitch effected by means of these four positions, however, is almost equal to that of the seven positions of the modern trombone. The tenor or ordinary trombone is given as an example. It stood in the first position in A. The second position, equal to the modern third produced the harmonic series of the fundamental G one tone lower than the first position. The third position gave F again a tone lower and corresponding to our sixth position. The fourth position, which extended so far outward “that the arm could hardly reach it,” gave E as fundamental. The intermediate semitones, instead of being considered as positions, are treated as accidentals, lowering or raising any note obtained in one of the positions by drawing out, or pushing in, the slide approximately an extra two-fingers breadth. It would not be correct to state without qualification that four positions only were used on the trombone in the 18th century.

Samuel Wesley, who has left notes on the scales of various instruments, in his own hand (Add MS. 35011 fol. 166 Brit. Mus.), has added under the scales of the trombones — bass, tenor and alto — the remark “sacbut or double trumpet, the scale of which is wanting.”

Of all wind instruments the trombone has perhaps been least modified in form; changes have occasionally been attempted, but for the most part with only trifling success. The innovation which has had the most vogue dates from the end of the 18th century; it consisted in bending the tube of the bell in a half circle above the head of the executant, which produced a very bizarre effect. It also gave rise to very serious inconveniences: by destroying the regularity of the proportions of the bell it prejudicially affected the quality of tone and intonation of the instrument. For a long time the curved bell with its serpent's mask known as the Bucin — a term borrowed from the French in this instance — was maintained in military music, and it is not so very long since it was completely given up. By giving a half turn more to the bell tube its opening was directed to the back of the executant; but this form, in fashion for a little while about 1830, was not long adhered to, and the trombone reassumed its primitive form, which is still maintained. As appears from a patent deposited by Stölzel and Blümel at Berlin on the 12th of April 1818 the application of ventils or pistons was then made for the first time.[4] The ventils, at first two in number, effected a definite lengthening of the instrument. The first augmented the length of the tube by a tone, lowering by as much the natural harmonics. The second produced a similar effect for a semitone, and the simultaneous employment of the two pistons resulted in the depression of a tone and a half. The principle, therefore, of the employment of ventils or pistons is the same as that which governs the use of slides (see Valves). Notwithstanding the increased facility obtained by the use of pistons, they are very far from having gained the suffrage of all players: many prefer the slide, believing that it gives a facility of emission that they cannot obtain with a piston trombone. The flat tonalities having been preferred for military music since the beginning of the 19th century the pitch of each variety of trombones has been raised a semitone. At present six trombones are more or less in use, viz. the alto trombone in F, the alto in E♭ (formerly in D), the tenor in B♭ (formerly in A), the bass in G, the bass in F (formerly in E), the bass in E♭ (formerly in D), and the contrabass in B♭. This transposition has no reference to the number of vibrations that may be officially or tacitly adopted as the standard pitch of any country or locality. A trombone an octave lower than the tenor has recently been reintroduced into the orchestra, principally by Wagner. The different varieties just cited are constructed with pistons or slides, as the case may be.

Further information on the trombone will be found in the monographs by the Rev. F. W. Galpin, “The Sackbut: its Evolution and History,” Proc. Mus. Assoc. (1906-1907); by Victor Mahillon, Le Trombone, son histoire, sa théorie, sa construction (Brussels, London, 1907). Before his recent death Professor George Case had in preparation an important work on the trombone.


TROMP, the name of two famous Dutch admirals.

1. Martin Harpertzoon Tromp (1597-1653) was born at Brielle, South Holland, in 1597. At the age of eight he made a voyage to the East Indies in a merchantman, but was made prisoner and spent several years on board an English cruiser. On making his escape to Holland he entered the navy in 1624, and in 1637 was made lieutenant-admiral. In February 1639 he surprised, off the Flemish coast near Gravelines, a large Spanish fleet, which he completely destroyed, and in the following September he defeated the combined fleets of Spain and Portugal off the English coast — achievements which placed him in the first rank of Dutch naval commanders. On the outbreak of war with England Tromp appeared in the Downs in command of a large fleet and anchored off Dover. On the approach of Blake he weighed anchor and stood over towards France, but suddenly altered his course and bore down on the English fleet, which was much inferior to his in numbers. In the engagement which followed (May 19, 1652) he had rather the worst of it and drew off with the loss of two ships. In November he again appeared in command of eighty ships of war, and a convoy of 300 merchantmen, which he had undertaken to guard past the English coast. Blake resolved to attack him, and, the two fleets coming to close quarters near Dungeness on the 30th of November, the English, after severe losses, drew off in the darkness and anchored off Dover, retiring next day to the Downs, while Tromp anchored off Boulogne
