Here's a starting template:

%%%  CODE ENDS
\version "2.9.14"

\paper
{
        indent = 0\in
        ragged-right = ##t
}

tremoloMusic = \relative c''
{
        \time 3/4
                \repeat "tremolo" 1 { c8 d8 }
                \repeat "tremolo" 2 { c8 d8 }
        \time 6/8
                \repeat "tremolo" 3 { c8 d8 }
        \time 4/4
                \repeat "tremolo" 4 { c8 d8 }
        \break
        \time 6/8
                \repeat "tremolo" 1 { c16 d16 }
                \repeat "tremolo" 2 { c16 d16 }
                \repeat "tremolo" 3 { c16 d16 }
        \time 6/4
                \repeat "tremolo" 4 { c16 d16 }
                \repeat "tremolo" 8 { c16 d16 }
        \break
        \time 5/8
                \repeat "tremolo" 1 { c32 d32 }
                \repeat "tremolo" 2 { c32 d32 }
                \repeat "tremolo" 3 { c32 d32 }
                \repeat "tremolo" 4 { c32 d32 }
}

\score
{
        \tremoloMusic
}
%%%  CODE ENDS

Key points to remember:
    1. The duration of the note(s), e.g., c32, will determine the  
duration of the tremolo (e.g., how many beams will be printed).
    2. The overall length of the resulting tremolo will be the  
combined duration of the alternating notes (i.e., inside the {}  
brackets) multiplied by the \repeat parameter -- e.g., \repeat  
"tremolo" 4 { c32 d32 } will be 4 x (2 x 32nd) = 4 x 16th = 1 quarter  
in duration, as seen in the final template example.

Best regards,
Kieren.
