I feel bad that this came up with you, Paul: I have a great deal of respect for your arrangements and your playing - you pay more attention to the composer's intentions than almost any other arranger.
I appreciate that both of you took a calmer and friendlier tone in your posts than I did in my last one. I apologize if I came across as rude. Excessive interpretation added to music is a real hot-button issue for me.
And for things you write down there is no standard interpretation either. Just as an example: There are terms like staccatissimo, staccato, half-staccato, leggiero, portato, legato, legatissimo... What do all these terms mean for the exact duration of a note
Part of the problem here is that
for a given time period and a given instrument, there often is a standard interpretation -- but it's not the same for every instrument. The other part of the problem is that when we write for computers, we have to give instructions for things like "exact duration" while when we write for humans, we give instructions for physical actions.
If you want to give a string player exact instructions, you need to tell him whether he begins a note by striking the string, or with his bow already on the string; and whether he ends it by letting the bow bounce freely (if the string was struck), by lifting the bow, by stopping the bow while it's on the string, or by keeping the bow moving until the next note begins. The length of the note is a consequence of the physical action. Similarly if you want to give a woodwind player exact instructions, you tell him whether he tongues the beginning of each note (necessarily creating a space between notes) or blows continuously.
There are words to write in the parts for these things - but they are not used much because within a given genre the interpretation is very standardized.
A particular problem for computer playback is that to a string player, the tenuto mark usually means "stop the bow on the string, creating a tiny bit of space between this note and the next" -- that is, make the note distinctly
shorter than a fully legato note, but not nearly as short as staccato -- while to a keyboardist it may mean to hold the note extra long. Same kind of story for staccato-under-a-slur: keyboard conventions are different (and non-keyboardists often won't know the keyboard conventions just as the keyboardists won't know string conventions.) Some computer software lets you specify how to translate articulation marks into note lengths -- but I don't know of any that lets you specify different rules for different instruments.
I have the feeling that accordion never quite got to the point of having its own set of widely agreed conventions, which is part of why it's hard to write precisely for accordionists.
If the staccato were half then a staccato quarter note would be the same as an eight note followed by an eight rest.
If the tempo is slow enough that one can hear the difference between a staccato (left to player's interpretation) quarter and an eighth, yes, one needs to choose which to write. (Incidentally, in a string part, we're likely to interpret a staccato quarter in slow tempo as lifting our bow and letting the note ring, vs. eighth - eighth rest as an instruction to stop our bow on the string and kill the sound.)
Frosini is particularly commendable in this regard. Even in a fast 6/8 he is careful to distinguish quarter-eighth from eighth - eighth rest - eighth. Not many people will take the trouble to write out 100 eighth rests.
Still, it is just enough to allow skilled musicians to play the notes and think for themselves how to play the notes so they become music.
I think where we differ is that you expect the musicians to take some considerable time thinking about these choices. As a composer, if I don't write in those details, it's because I think there is
one obvious interpretation and I expect players to default to what I want without me telling them. If I put it in front of a player and they do something different than I expect, I am going to be revising the music to make my intentions clearer.
I must be very fortunate in knowing many amateurs who can do much better than a computer realization.
There are fewer ways to play an accordion badly than there are to play a violin or a horn badly. If you push the right button and move the bellows, something quite close to the intended sound comes out.
My computer is a much better violinist than I ever was, even after playing for 30 years. I test passages on my violin to see if bowings and fingerings work, but not to hear what they sound like, not unless I want to sink the whole afternoon into trying to get it to sound good enough I don't want to cover my own ears.
It has been an exciting new thing for me, that on accordion, I can actually pick up the instrument and try something out to see how it sounds.
take Sinatra, everybody covers him mostly on the count, but he was rarely on the count. But these minute differences are almost impossible to put down on paper unless you go down to 1/64th notes or something
This is what gives character and identity to a performance.
Here we are solidly in we'll-have-to-agree-to-disagree territory.
If your name isn't Frank Sinatra, not being on the count generally means you need to learn how to count better before you inflict yourself on the public. If your name isn't Bob Dylan, not being in tune generally means you need to learn how to sing in tune before you inflict yourself on the public.
When famous musicians get away with, and get rewarded for, doing stuff that any beginner would be scolded for doing, it takes away from my enjoyment of the music, doesn't add to it.
In rehearsal you can get a handle on that, and you will stray away from the dots a lot of the time
Here again our experiences are wildly at variance.
The vast majority of my private practice time, and my ensemble rehearsal time, is about getting closer to the dots, not farther from them.
Re specifically being on the beat - a particular difficulty of instruments like tubas and french horns is that they are a little bit slow to speak (as well as often being placed at the back of the stage, about 1/40th of a second farther from the audience than the violins) and quite often they need admonished to anticipate the beat a bit in their heads, so that their actual sound production coincides with the beat.
I was mercifully spared the need to do that, playing violin -- but I have come face to face with that problem with the bottom octave of my L reeds on my accordion: they are so slow to speak the button needs pressed something like a sixteenth note early if I want to hear the sound on time. It is really hard to get a legato sound in that register since it requires some overlapping of the time the keys are depressed, rather than just taking care not to release one key before depressing the next.
Ah, to have one of the better quality instruments that would alleviate at least some of that.
