HOW to make a piano reduction with multiple voices and rhythms ?


Recommended Posts

Dear All,

 

Very clear question:

 

HOW to make a piano reduction with multiple voices and rhythms ?

Like a reduction of a string quartet poliphonic material with 4 voices:

ALL RHTYHMS INDEPENDENT with their own pauses.

With the typical arrangement of stems for voice separation:

 

TREBLE CLEF - voice 1 stems up

TREBLE CLEF - voice 2 stems down

BASS CLEF - voice 3 stems up

BASS CLEF - voice 4 stems down

 

Any help ?

Please, help !

Quite simple to do:

Thank you, guys !!

You are amazing !!

 

But I got some errors...

Janusz, on your 1st possibility I got this error:

80 >

On the 2nd possibility I got this error:

I don't know what happened

 

Thanks again !!

One thing

 

COMMAND+E in the  expression below works ok

 

(setf bass
      '((-h. q g3) (e c4 bb3 q a3 e g3 f3 q eb3) (h. d3 fermata q c3)
        (q bb2 a2 g2 c3) (h. d3 fermata q d3)
        (q g3 e f3 eb3 d3 c3 q bb2) (q eb3 f3 gb3 fermata d3)
        (q g3 a3 e bb3 a3 g3 f3) (q eb3 f3 bb2 fermata bb3)
        (q a3 bb3 gb3 e g3 f3) (q e3 c3 f3 fermata f3)
        (q bb2 e c3 d3 q eb3 e d3 c3) (h d3 q g2 fermata)))

BUT......

COMMAND + 1 (to make a snippet) give me this error:

 

> Error: OMN Parse Error: fail
> While executing: omn-to-ast, in process Listener-1(7).
> Type cmd-. to abort, cmd-\ for a list of available restarts.
> Type :? for other options.
83 > 

 

So, I copied the tenor part and trasposed it -7 (just for test...)

 

and got this error:

85 > 
85 > 
85 > 
> Error: Unbound variable: 
> While executing: ccl::toplevel-eval, in process Listener-1(7).

piano-layout + merge-voices

(no idea about the stems, use notation software for layouting?)

 

 

Thanks, André !

It works, but looks ugly. The absense of stems up and down make it illegible.
