Before this invention the interval of three whole tones (Triton) was considered an intolerable dissonance and was called "the devil in music." The dominant seventh has been the open door to all dissonances and to the domain of expression. It was a death blow to that learned music of the sixteenth century; it was the arrival of the reign of melody—of the development of the art of singing. Very often the song or the solo instrument would be accompanied by a simple, ciphered bass, the ciphers indicating the chords which he who accompanied should play as well as he could, either on the harpsichord or the theorbe. The theorbe was an admirable instrument which is now to be found only in museums,—a sort of enormous guitar with a long neck and multiple strings which offered great opportunities to a skilful artist.
It is curious to note that in ancient times there was not attributed to the minor and major keys the same character as is assigned them to-day.[2] The joyous canticle of the Catholic church, "O Filii et Filiæ," is in the minor. "The Romanesca," a dance air of the sixteenth century, is equally in the minor, just like all the dance airs of Lully, and of Rameau, and the gavottes of Sebastian Bach. The celebrated "Funeral March" of Haendel, reproduced in many of his works, is in C Major. The delicious love duo of Acis and Galathee, which changes to a trio by the addition of the part of Polyphemus, is in A Minor. When Galathee weeps afterward over the death of Acis, the air is in F Major. It is only recently that we find dance airs in the major mood or key.
From the seventeenth century on, music entered into everyday life, never again to be separated from it. Thus music has remained in favor, and we are continually hearing executed the works of Bach, of Haendel, of Hayden, of Mozart and of Beethoven. How are such works executed? Are they executed as they should be? That is another question.
One source of error is found in the evolution which musical instruments have undergone. In the time of Bach and Haendel the bow truly merited its Italian name of "arco." It was curved like an arc—the hairs of the bow constituted the chord of the arc, a very great flexibility resulting which allowed the strings of the instrument to be enveloped and to be played simultaneously. The bow seldom quitted the strings, doing so only in rare cases and when especially indicated. On this account it happens that the indication of "legato" is very rare. Even though there was a separate stroke of the bow for each note, the notes were not separated one from the other. Nowadays the form of the bow is completely changed. The execution of the music is based upon the detached bow, and although it is easy to keep the bow upon the strings just as they did at the commencement of the nineteenth century, performers have lost the habit of it. The result is that they give to ancient music a character of perpetually jumping, which completely destroys its nature.
The very opposite movement has been produced in instruments of the key or piano type. The precise indications of Mozart show that "non-legato," which doesn't mean at all "staccato," was the ordinary way of playing the instrument, and that the veritable "legato" was played only where the author specially indicated it. The clavecin or harpsichord, which preceded the piano, when complete with two banks of keys, many registers giving the octaves and different tone qualities, oftentimes like the organ with a key for pedals, offered resources which the piano does not possess. A Polish lady, Madame Landowska, has studied thoroughly these resources, and has shown us how pieces written for this instrument thus disclosed elements of variety which are totally missing when the same are played upon the piano; but the clavecin tone lacked fulness, and shadings or nuances were out of the question.
Sonority or tone was varied by changing the keys or register just as on the organ. On the other hand, with the piano one can vary the sonority by augmenting or diminishing the force of the attack, hence its original name of "forte piano,"—a name too long, which was shortened at first by suppressing the last syllables; so that one reads, not without astonishment, in the accounts given of young Mozart, of the skill he showed in playing "forte" at a time when he was playing on instruments of a very feeble tone. Nowadays when athletic artists exert all their force upon the modern instruments of terrific sonority, they are said to play the "piano" (toucher du piano).
We must conclude that the indication "non-legato" finally degenerated into meaning "staccato." In my youth I heard persons advanced in age whose performance on the piano was extremely dry and jumpy. Then a reaction took place. The tyrannical reign of the perpetual "legato" succeeded. It was decided that in piano playing unless indicated to the contrary, and even at times in spite of such indication, everything everywhere should be tied together.[3] This was a great misfortune of which Kalkbrenner gives a manifest proof in the arrangement he has made of Beethoven's symphonies. Besides, this "legato" tyranny continues. Notwithstanding the example of Liszt, the greatest pianist of the nineteenth century, and notwithstanding his numerous pupils, the fatal school of the "legato" has prevailed,—not that it is unfortunate in itself, but because it has perverted the intentions of musical authors. Our French professors have followed the example of Kalkbrenner.
The house of Breitkopf, which until lately had the best editions of the German classics, has substituted in their places new editions where professors have eagerly striven to perfect in their own manner the music of the masters. When this great house wished to make a complete edition of the works of Mozart, which are prodigiously numerous, it appealed to all who possessed manuscripts of Mozart, and then having gathered these most precious documents, instead of reproducing them faithfully, that house believed it was doing well to leave to the professors full liberty of treatment and change. Thus that admirable series of concertos for piano has been ornamented by Karl Reinecke with a series of joined notes, tied notes, legato, molto legato, and sempre legato which are the very opposite of what the composer intended. Worse still, in a piece which Mozart had the genial idea of terminating suddenly with a delicately shaded phrase, they have taken out such nuances and terminated the piece with a forte passage of the most commonplace character.
One other plague in modern editions is the abuse of the pedal. Mozart never indicated the pedal. As purity of taste is one of his great qualities, it is probable that he made no abuse of the pedal. Beethoven indicated it in a complicated and cumbersome manner. When he wanted the pedal he wrote "senza sordini," which means without dampers, and to take them off he wrote "con sordini," meaning with dampers. The soft pedal is indicated by "una corda." The indication to take it off, an indication which exists even now, was written "tre corde." The indication "ped" for the grand pedal is assuredly more convenient, but that is no reason for making an abuse of it and inflicting it upon the author where his writing indicates the contrary.
As it seems to me, it is only from the eighteenth century that authors have indicated the movements of their compositions, but the words which they have employed have changed in sense with time. Formerly the difference between the slowest movement and the most rapid movement was much less than at present. The "largo" was only an "adagio" and the "presto" would be scarcely an "allegro" to-day.
