“Music is a moral law. It gives a soul to the universe, wings to the mind, flight to the imagination, a charm to sadness, and life to everything. It is the essence of order, and leads to all that is good, just and beautiful, of which it is the invisible, but nevertheless dazzling, passionate, and eternal form.”

Legato at the Piano: Music is not a Democracy

     
A pianist writes asking for clarification regarding my views on producing legato at the piano. I have in the past startled the unwary by stating that legato on the piano is in fact an illusion. The piano is a percussion instrument. Sorry. That's a fact. It's about physics. (I shall now take cover under my very sturdy Mason and Hamlin BB, built in 1926 and weighing more than 1000 pounds.)
          We can create whatever imagery we like in order to help with our illusions—imagination is good—but the fact remains, a hammer hits a wire. That's percussive—not quite on the order of a snare drum, but, well you get the picture. The wire vibrates, which in turn causes the air around it to vibrate sympathetically. This vibrating air is what tickles our ears.
     Some pianists, even distinguished ones—I'm thinking now of Alfred Brendel—feel that by wiggling the finger on the key surface after striking it, a sort of pitched vibrato occurs, a violin-like effect. The hope is, as I understand it, that the sound will have more warmth and perhaps seem more connected to the next pitch. I'm sorry to have to report that only the key wiggles in its bed; the hammer has done its job and moved away. Once the  hammer has struck the string, only God can change it, that is, until we release it. Some may argue that it's the intention of the attack that counts. If the key is depressed with the intention of vibrating afterwards, the sound may be affected. This argument seems weak to me.
     Side note: Years ago (meaning half a century), I had the opportunity to hear my piano teacher, Muriel Kerr, play the Brahms
Jascha Heifetz, violin
C Minor Piano Quartet with Heifetz, Primrose and Piatigorsky. For my younger readers, they were the superstar string players of the 20th century. It was my first time hearing the work, and I was, of course, stunned by its drama and lyricism. Not long after that, I found myself engaged for a
William Primrose, viola
performance of the same piece and, looking at the score for the first time, I noticed that the piano starts with a forte octave tied over two bars with a diminuendo to 
piano for the entrance of the strings.  This diminuendo must take place in tempo, an Allegro non troppo. So I puzzled over how to make a quicker diminuendo. You've probably already guessed the answer.

Inexperienced as I was, though, I had to ask Miss Kerr. She was glad to oblige, and with a giggle, struck the octaves and allowed them to ring for most of the first measure, then  released the keys part way and fluttered the pedal for the

remaining three beats, releasing the keys even more. It was a perfect diminuendo from forte to piano in exactly the right amount of time, controlled by the pianist. No need to bother God about it.

      Now back to our regularly scheduled topic.
      I have written about producing the illusion of legato on the piano by, for example, playing into the decay of each successive note. This is perhaps the closest we can come to the sort of legato a string player can manage, or a singer. Of course, though, this approach produces a pronounced diminuendo, which is not always the desired effect. 
     My correspondent quotes Samuil Feinberg's book, which  "argues that the acoustical illusion of legato has actually more to do with joining together the initial sounds (the immediate sound of the attack), rather than their decay, because if not, he argues, all legato would be diminuendo. And so then, how do you create illusion of legato in a crescendo cantabile line." This is the question we deal with on a daily basis. Feinberg solves this dilemma by "joining the beginnings of each sound, or at least the memory of it."
     Exactly right. Music is not a democracy. Every note does not get an equal vote. Feinberg is right. I call this the hierarchy of notes. We must have the musical idea of the line in mind as we play the first note. What are the dynamic relationships?  In a lyrical crescendo, each attack of each successive note must be louder in relation to the initial attack of the previous note. 
      I think the manner of attack is the most important issue in a moving legato line, that is, play from the key, minimizing downward speed of the key. This removes much of the "attack," but we can still control the dynamic with weight. When Feinberg states that legato is the result of "joining initial sounds," I think he is referring to hierarchy, or put another way, the audible shape of a line. If we take care to control each dynamic ascent in the right relationship to the initial attack of the previous one, controlling the speed of descent into the keybed, a convincing facsimile of legato occurs. Imagine a string of beads in which each bead is graduated from smaller to larger in carefully managed increments.
