<p>This table shows seven columns of <a href="//commons.wikimedia.org/wiki/File:Scales_on_keyboard.svg" title="File:Scales on keyboard.svg">File:Scales on keyboard.svg</a>, but arranged in a rather subjective way.
</p><p>The semitone pairs <i>ti-do</i> and <i>mi-fa</i> are grouped together, and so is the pair <i>so-la</i>. The remaining <i>re</i> is shown alone.<br>
The resulting pattern can help to learn the positions of the tones in each scale.
</p><p>An easily seen regularity is that the semitone pair is usually black-white for ♯ scales and white-black for ♭ scales.
</p><p>An intuitive way to play this is as a downward minor scale (with a <i>la</i> to be added at the end):<br><i>la-so ... fa-mi ... re ... do-ti ... (la)</i>
