software > Accelerando

Accelerando is a musical metronome that can speed up, allowing you to practice your music at progressively faster tempos. For example, you could set it to play 60 beats per minute for 4 bars, then automatically speed up by 10 beats per minute, and so on. It runs on Unix.

This program has some dependencies, which can be satisfied with the following debian packages:

1. alsa-utils or madplay -- required
2. libgtk2-perl -- optional; needed if you want to use the GUI rather than the command-line interface
3. festival -- optional; needed for speech-synthesis features

generic instructions for installing Accelerando

download Accelerando 1.1

Download the source code, and then do this:

  tar -zxvf accelerando.tar.gz
  cd accelerando-1.1
  make install

You also need to install the dependencies listed above, e.g., by doing apt-get install alsa-utils libgtk2-perl festival.

The program's man page is reproduced on this web page.

For anyone who wants to see the very latest version of the program, or who wants to contribute to the project, I have a public Git repository here.

NAME
       Accelerando - an accelerating musical metronome

SYNOPSIS
       accelerando &
               Runs the GUI.

       accelerando -t
               Prints usage information for the command-line interface.

       accelerando -t argument-list
               Runs the command-line interface. The argument list can be
               truncated, in which case the missing parameters take their
               default values. A default value can also be specified with a
               dot.

       accelerando -v
               Prints the version number and exits.

ARGUMENTS
       initial tempo
               Initial tempo, in beats per minute.

       wait    Seconds to delay before starting.

       timesig Beats per bar

       bars    Number of bars before increasing the tempo

       add     Amount to add to the tempo after the first time. If a maximum
               tempo has been set, the tempo will not keep increasing at this
               rate forever, but rather will asymptotically approach the
               maximum tempo.

       max     Maximum tempo.

       voice   If this parameter is set to 1, a synthesized voice will
               announce each tempo.

       interpolate
               If set to 1, the tempo will go up smoothly rather than
               discontinuously at the end of each repetition. Default: 1.

DESCRIPTION
       Accelerando is a musical metronome that can speed up, allowing you to
       practice your music at progressively faster tempos. For example, you
       could set it to play 60 beats per minute for 4 bars, then automatically
       speed up by 10 beats per minute, and so on.
