Guest columnist, Josephine Gibson, is taking time from her busy farming activities today to respond to a reader’s question. I'd like to thank her for washing her paws before she takes over the MacBook.
I. Stravinsky from Hollywood, CA asks:
"How long is an 8th-note? I am having difficulty getting the proper length and distinction without writing articulations over every note."
Jojo responds: Thanks for the question, Isabelle; I recognize your handwriting. Do you remember that we met at conference last year? You were asking about the length of a 16th, I came up with a hairball (just send me the bill, please). Well, as you may recall from that chat, I offered the view that musical notation, being a language, is approximate in meaning. It cannot be translated or interpreted with absolute precision. So it is with an 8th-note. Its length depends on many factors, including the context within a piece, within a stylistic/historical period, or within a composer’s oeuvre. Not to mention the size and acoustic of the performance space. My dad, Mark, is working now on Brahms 2 and is urging the orchestra to play very long 8th’s, but just last month he was conducting Mozart 29 and sometimes couldn’t get the 8th’s short enough. It also depends, in string playing, on vibrato. Sometimes Dad asks the violins to add one or two “shakes” of vibrato to a note; I guess he uses that to give an 8th-note length and quality. It also makes it sound pretty ☺. He occasionally quotes his old piano teacher, Theodore Lettvin, saying that an 8th-note can be anywhere between a "5th"-note and a "15th"-note in length. I don't know; I've never seen a 15th-note, but I guess he meant that it can be nearly as long as a quarter note or nearly as short as a 16th-note.
Meanwhile, if there is a dot over the 8th, what does that mean? Dad encourages the orchestra to define the dot - indicating “staccato” - as “separated,” as opposed to merely “short.” The Italian infinitive, “staccare,” means, “to detach.” How short? As Pitti-Sing from “The Mikado” says, “Bless you, it all depends!” I think that the composer can add all the articulations s/he wants to an 8th-note passage, but every musician will arrive at a different conclusion as to what they mean.
CONTEXT and TASTE. These are among the primary factors to consider when establishing the length of an 8th-note, articulations not withstanding. It is the conductor's job, as the arbiter of taste, to define thoughtfully how the ensemble will execute 8th's. Let's hope that Maestro did his/her homework!
Thanks for the question, Isabelle. Dad, can I get back to the farm now? I've got sugar beets to harvest.
