RE: Transpose

I appreciate your thoughts on this one. I was looking for ways to avoid repeating my code and therebye reduce the size of the LP file - I have 26 scales to cover! I thought it might be possible to have a basic brocken chord exersice in C and then simply transpose each scale from that. Utopia…

I have decided that in the long run it will be quicker and less effort to write out each scale (longhand). I enclose my basic structure. If you have a better idea, please let me know.

I'm not sure how you expect LP to divine the range of the clarinet.

What *would* be a "strange interpretation" to me is transposing an

interval of a sixth into a fourth.

But the solution to your particular problem might be to observe

that most of the notes in your manually adjusted version (senza

typo) are shifted in time by one group when compared with the

correct (your so-called "wrong") version. Also, several of the

groups (corresponding to lines in the source file) are exact

repetitions.

So I would break your Cmajor variable into 4-note chunks and then

build each sequence from these smaller variables. Note that for

this to work, you must put \relative { } round the composite

scale, not round the 4-note chunks. The latter must be left

"floating", neither absolute nor relative.

%% ✄ %%%%

raw = { c16 e f g }

\score {

\relative c' { \raw \raw \raw \raw }

}

baked = \relative { c e f g }

\score {

\relative c''' { \baked \baked \baked \baked }

}

%% ✄ %%%%

The \relative c''' is impotent in both its effects, because \baked

is already absolute.

The idea is to go ahead and repeat the exercise in G major, Eminor etc., however, it looks as though I am going to have to write everything out (longhand). You will see in my example that modalTranspose gives a strange interpretation of A minor and I wonder whether there is a solution to this?

Cheers,
