Metrico
Metrico is a font that allows to easily create metronome marks, metric modulations and swing indications for music notation.
Metrico is licensed under the SIL Open Font License. That means that it is free to use. However, developing fonts takes considerable time and effort, so if you regularly earn money with this font (by using it for commercial work or by selling a derivative of it on its own or as part of a larger work or collection), please consider supporting me with a donation via paypal.
