Piano sketch or not for orchestrating and composing

Context: composition of an orchestral work or, at least, a chamber piece.
Do you first use a sketch for solo piano?
What advantages would this have?

With the whole range of software and virtual instruments available, the temptation (and reality) of composing directly for the orchestra is very strong.

As an amateur composer who makes music purely for intellectual pleasure and for the senses, and also because I am partly self-taught and partly formally trained, I confess that the small pieces I have written have been without a piano sketch.

By piano sketch, I do not mean, in this case, a reduction for piano that is idiomatic for the instrument, even virtuosic. I mean a sketch that captures the basics: structure, harmony, melody, rhythms, accents.

I consider my training in classical and modern harmony to be very good. In counterpoint, quite good. But lately I have become interested in orchestration and, in turn, trying to structure a work of a certain length (without going overboard for the moment).

And in this sense, I think that the piano sketch can be very useful and not a waste of time.

In relation to this, I am also doing the opposite: orchestrating fragments or small pieces for solo piano.

What do you think?

Hi @Luis Hernández!

I personally use different numbers of staves to sketch things out for orchestra depending on how far I am in refining my material, what my needs are or how big the orchestral forces I'm sketching out are going to be.  If I'm sketching out for a string orchestra I usually don't need more than 3 staves (treble clef, alto clef and bass clef).  If I'm expanding the string orchestra sketch for a bigger orchestra I use 6 - 8 staves:  3 staves for the strings, 2 for winds, 2 for brass, and 1 for percussion.  Finally, if the score is really complex I will write things out for a full orchestra partiture upwards of 16 staves.  But I rarely use just a 2 stave piano score for an orchestra - for me it's too small.

I've heard that John Williams uses 8 staves when he sketches out his film scores.

Great topic!

I have heard that JW does use 8 staves, too @PeterthePapercomPoser.

Writing out a sketch would help me.  I am slowly learning orchestration (Adler's Tome is a lot to take in).   

My recommendation would be: master piano writing!  🙂 

It's good to see how others organise themselves.
The idea of working on the sketch in three staves or more, depending on the volume, is great.
Perhaps in a future project I will try to do the sketch for solo piano, as the intention is not so much to imagine orchestral colours as to establish the structure, parts, climax, harmony and rhythm.

During my studies I sometimes did the sketches but with the experience comes the inner ear skill. Today I can hear the orchestra before I even write notes down. I guess I would be able to be deaf like Beethoven and compose further, trusting my inner ear.

Piano sketches can be useful for beginners in composition because it keeps them focused on making sure the raw musical material is worth actually expanding into something big like an orchestra.

However, once you are skilled enough in simply "composing", and your familiarity with the orchestra grows, you tend to outgrow the sketch and see its very limited utility.

I actually sort of dislike the piano as an instrument, because it is really not very expressive and sterile, whereas the orchestra can play from whisper quiet to deafeningly loud and with a huge number of articulations that a piano simply cannot emulate. What can happen if you rely all the time on a piano sketch is that you will orchestrate the music in a very basic manner; no trills, horn rips, portamento, mordents or other ornamentation...because the piano is not really capable of it.

Another issue is that in orchestration, tone colour is of paramount importance and basically why you would use an orchestra in the first place. A melody played on the oboe can have an entirely different character than it would played by the horns; the piano captures neither.

Where this also manifests itself is in harmony. For example, in a piece I am presently working on, it begins with the horns playing a Gm add9, no5 chord at piano dynamics. This has a real warm, ethereal quality that the piano and sustain pedal couldn't capture. Thus, if I had reached for the piano instead of a horns patch in my DAW, I don't think I would've come up with the harmonic language the piece has.

Another thing is that: I compose for film. Two films I did this year I had just a few weeks to compose the score before the premieres in a major city. So there were hundreds of people counting on me to be on time.

I just don't have time to sketch things out in a piano and then try to translate it to an orchestra. Especially not in film, where the picture itself influences the structure and orchestration; makes way more sense to just go straight for the instruments you have in mind.

You can also get some sample libraries these days which are quite playable or at least set up a couple of patches to play in tandem (like staccato + long) and "sketch" that way, with the instrument sounds right at your finger tips. In notation software, you could play your melody on your keyboard, and then just enter it straight away to the violins. Don't like how it is on the violins after all? Copy/Paste it to the flutes in a second.

Piano sketches have their uses. Concert composers might still find use for it and beginners will value it, but modern technology has given us better alternatives, I find.

It should also be noted that composers of old often didn't really use a "piano" sketch even if they worked at a piano. Following what @Sojar Voglar said, John Williams' sketches were always 3-stave reductions for winds, strings and brass. So even when he was writing at the piano, he was pretty much orchestrating it at the same time. He was always composing with the orchestra in mind.
