Following my earlier posts covering an introduction to the notes on the guitar fretboard and some basic music theory, in this post I’ll provide some visualization tools to help provide some insight into the structure and layout of the notes on the guitar fretboard.

If you have a locally-hosted version of a web site for testing or development, you’ll almost certainly want to test it on a mobile device.

Let’s say the local site is hosted on Mac OS X, and you access it with a URL containing a hostname defined locally in the Mac’s “hosts” file, such as http://exampledev.com.

How can you test the site using the same URL on a mobile device (that is, a real mobile device, not an emulator)—without jailbreaking the device, using a DNS server, or paying for additional software? In this post I’ll describe a way to do exactly that.

Recently I looked at the layout of the notes on the guitar fretboard, and described a useful notation for showing the absolute pitch of each note, Helmholtz pitch notation, shown here:

Perhaps one of the more puzzling things for a newcomer to music theory is the apparently uneven distribution of “natural” notes: why are they next to each other in some places like E and F, and not in others like F and G?

To understand this, we need to take a step back and look at some basic music theory.

While you can get by playing chords and patterns on the guitar without knowing individual notes by name, at some point you probably want to learn the note names across the fretboard—perhaps in order to help remember what you’ve played, read and write music, and communicate with other musicians.

What follows is a basic introduction to the notes on the guitar fretboard, also known as the fingerboard. Later posts will cover some rudimentary music theory and visualization tools to help you to understand how the notes are arranged.
