Re: tremolo: 3/4 time, one dotted-half note chord, double-slash tremolo question

I also remained confused by this for a long time till I understood
that the rules are pretty simple. The thing to keep in mind is that
\repeat tremolo and : don't work the same.
The rules are:

- The appearance of the notes in a tremolo determines the
  total duration. (Even if there are two notes, they count
  for this duration once.)

- The beaming of the notes determines the duration of the
  notes in the fully developed form where you replace the
  tremolo notation with actual repeated notes, like
  \unfoldRepeats does.

- The number passed to \repeat tremolo is the number of
  times the pattern is repeated.

- In the syntax :, the
   is the total tremolo duration, and
   is the duration of one note in
  the developed form.


So your tremolo can be written as

\relative d' {
    \time 3/4
    d2.:16
}

as William suggested, or

\relative d' {
    \time 3/4
    \repeat tremolo 12 d16
}


since "duration of dotted half note / duration of sixteenth note = 12".

Best,
Jean

Re: tremolo: 3/4 time, one dotted-half note chord, double-slash tremolo question

[William Rehwinkel]

Hey Ken,

For a tremolo on a single repeating note you can use this other syntax:

\version "2.24.0"
\relative d' {
    \time 3/4
    d2.:16
}

Hi;

  I'm still do not understand the math (I'd like to generate a

  I have a tremolo that I'd like to engrave in 3/4 time, one

Re: tremolo: 4/4 time, 2 half notes, single-slash tremolo question

[William Rehwinkel]

Great, glad you could get it working Kenneth. Speaking for myself, I 
found it easiest to think of \repeat tremolo in the same way as the 
other \repeat commands... the first number is how many times the note 
repeats.

tremolo question; don't understand how to apply the manual to my situation

[Kenneth Wolcott]

Hi;

  I have a tremolo question.

  4/4 time
  bass clef (piano part)
  polyphony apparently required
  two half notes, the first half note is in both voices

  I don't understand the tremolo repeat section in the manual, and
definitely not when it comes to this situation.  See attached
screenshot.

  Here's my code (without the tremolo) for this measure (bass clef only):

  <<
{ e,2 e | } % tremolo??
  \\
{ e,2 ~ e,4 r | }
  >> % m17

Mike,

Not sure it will look "perfect" or "better" but, did you mean something 
like this?


\version "2.19.80"

\language "english"

\new Staff {

  \clef bass
  \relative c

  \repeat tremolo 8 {
    \override Beam.positions = #'(0 . 1)
    bf,16 b' }
}


Maybe  \override Beam.positions = #'(-1 . 1)  is what you want?
You want a slant or actually closer to the note itself?

I think what you had was close...

Of course they can!

No, it’s not meaningful (or rather, there’s no notation for that). I
