Where can I find a metronome for music practice?

Solution 1:

As mentioned in a comment, I couldn't get the mentioned metronomes (existing for Linux/Ubuntu) working on 16.04, at least not out of the box. I didn't spend much time in getting it to work, since practically all of them give the impression to be abandoned.

Time to write one...

This answer (work in progress) should eventually lead to a metronome, including GUI. A good time to mention possible features you'd like.

1. CLI metronome

Creating a straightforward metronome turns out to be shockingly simple:

#!/usr/bin/env python3
import subprocess
import sys
import time

bpm = int(sys.argv[1])
pauze = 60/bpm

while True:
    time.sleep(pauze)
    subprocess.Popen(["ogg123", "/usr/share/sounds/ubuntu/stereo/bell.ogg"])

How to use

1. The metronome needs vorbis-tools, to play the sound

   sudo apt-get install vorbis-tools
   

2. Copy the script above into an empty file, save it as metronome.py

3. Run it with the bpm as argument:

   python3 /path/to/metronome.py <bpm>
   

   e.g.:

   python3 /path/to/metronome.py 100
   

   To run it with 100 beats per minute

Note

For the sound, I used the file /usr/share/sounds/ubuntu/stereo/bell.ogg, which should be on your system by default (tested 14.04/16.04). You can however use any (.ogg) sample you like. In the final version, A number of options (sounds) will be available.

2. Shockingly simple GUI version

As a next step, a very basic version, the last version without an installer:

The script

#!/usr/bin/env python3
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import sys
import subprocess
import time
from threading import Thread
import os

path = os.path.dirname(os.path.realpath(__file__))

class MetroWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Shockingly simple Metronome")
        self.speed = 70
        self.run = False
        # maingrid
        maingrid = Gtk.Grid()
        maingrid.set_column_homogeneous(True)
        maingrid.set_row_homogeneous(False)
        maingrid.set_border_width(30)
        self.add(maingrid)
        # icon
        image = Gtk.Image(xalign=0)
        image.set_from_file(os.path.join(path, "icon.png"))
        maingrid.attach(image, 0, 0, 1, 1)
        # vertical slider,  initial value, min, max, step, page, psize
        self.v_scale = Gtk.Scale(
            orientation=Gtk.Orientation.VERTICAL,
            adjustment=Gtk.Adjustment.new(self.speed, 10, 240, 1, 0, 0)
            )
        self.v_scale.set_vexpand(True)
        self.v_scale.set_digits(0)
        self.v_scale.connect("value-changed", self.scale_moved)
        maingrid.attach(self.v_scale, 1, 0, 2, 1)

        self.togglebutton = Gtk.Button("_Run", use_underline=True)
        self.togglebutton.connect("clicked", self.time_out)
        self.togglebutton.set_size_request(70,20)
        maingrid.attach(self.togglebutton, 3, 3, 1, 1)

        # start the thread
        self.update = Thread(target=self.run_metro, args=[])
        self.update.setDaemon(True)
        self.update.start()

    def scale_moved(self, event):
        self.speed = int(self.v_scale.get_value())

    def time_out(self, *args):
        if self.run == True:
            self.run = False
            self.togglebutton.set_label("Run")
        else:
            self.run = True
            self.togglebutton.set_label("Pauze")

    def pauze(self):
        return 60/self.speed

    def run_metro(self):
        soundfile = "/usr/share/sounds/ubuntu/stereo/bell.ogg"
        while True:
            if self.run == True:
                subprocess.Popen([
                    "ogg123", soundfile
                    ])
            time.sleep(self.pauze())

def run_gui():
    window = MetroWindow()
    window.connect("delete-event", Gtk.main_quit)
    window.set_resizable(False)
    window.show_all()
    Gtk.main()

run_gui()

The image

How to use

1. Like the cli version, this one needs vorbis-tools:

   sudo apt-get install vorbis-tools
   

2. Copy the script into an empty file, save it as metro.py

3. Right- click on the image above, save it In one and the same directory as the script (exactly) as: icon.png.

4. Simply run the metronome by the command:

   python3 /path/to/metro.py
   

3. PPA for the Orange Metronome

It is done!

The metronome is ready for installation.
The Orange Metronome comes with a set of different sounds to choose from, and the beats can be grouped. All changes are applied immediately on the running metronome:

To install:

sudo apt-add-repository ppa:vlijm/orangemetronome
sudo apt-get update
sudo apt-get install orangemetronome

Work to do

• Currently, the metronome comes with four different sounds to choose from. Probably a few will be added in the next few days, some of them will be replaced/updated

• On the longer term
  For the longer term, I am thinking of adding the option for (custom) complex structures like 3+3+2, 2+2+2+3 etc., which I always missed in existing metronomes.

Finally

The latest (current) version 0.5.3 adds a number of sounds, but more importantly, the option to run irregular (composite) beats. In this version, they are hard coded. Will be customizable from version > 1.

Solution 2:

It sounds like you're looking for a metronome!

The audio-editing software Audacity can generate a steady, metronome-like beat or tone (look under the "Generate" menu), though there are simpler programs that I'll list below. Audacity is in the Ubuntu software repositories and can be installed through the Software Center or by typing sudo apt install audacity in a terminal window.

Online metronomes are plentiful, if you plan on having internet access during your practice.

Other metronome software available in the Ubuntu software repositories includes gtick, klick, gtklick, and kmetronome, though I haven't tried any of them myself.
