Each image below shows a chromatic scale from C to C in a particular alternative music notation system. For a general introduction see the Guided Tour. Click the button below for controls that let you select which systems are displayed and change how they are sorted. For example, deselect a checkbox to filter out all the systems that have that particular characteristic.
As an educational and informational resource, we seek to present these music notation systems in a fair and even-handed way. Unless otherwise noted, they each meet all of our desirable criteria for alternative music notation systems. A number of additional systems that take different approaches are listed on our More Notation Systems page. If you have designed a music notation system, and would like us to consider adding it to our site, see For Notation Designers.
