Peaceful tuning, Pacifica 112

Hello again! It's been over a year since my last post (Pure Drumming) . I started Electric Penguinland as a series of notes-to-self, to write up things that were difficult to discover online. I'm glad people have found the odd thing I've posted useful, so I'm picking up with the article that I was planning to start last year with: replacing the tuners on a Yamaha Pacifica.

Pure drumming

All too often I find ways to distract myself when I've intended to do some guitar practice. Recently I thought it would be nice to create some drum tracks to play with. "No problem!" You say, "Use Hydrogen ." This is a start, but what if you don't know much about drumming and find clicking beats on a track comes out a bit flat? The first thing to come to mind was to try some MIDI pads, but that seemed like overkill, especially when something with buttons on it was much closer to hand—my Xbox 360 controller.

MathJax posts

My posts on the string bend calculator used MathJax to display the equations used. But I ended up struggling a while to get them to work on mobile devices. The problem is this: typically MathJax loading needs to go into the document head, but that means editing your blog template.

Making the pitch - tuning

Guitar pitch pipes, Wikimedia If you play guitar then you need to tune it from time to time, unless you're deeply in to experimental music.

Bending with Dojo part 1: Maths rock

One of the distinctive sounds of the guitar is bending notes, pushing or pulling the string sideways across the fretboard to raise its pitch. Santana's Samba Pa Ti and Pink Floyd's Shine On You Crazy Diamond have classic examples, but whether you're listening to BB King or Noel Gallagher it'll show up from time to time. But guitar strings are steel, they can't stretch that much can they? Some people have trouble believing this and think there must be 'give' somewhere else, but a guitar string is thin and long and really can stretch, so I thought I'd put together a string bend calculator to show how. Using it should be self explanatory, this series of posts is about what's happening under the hood.

Bending with Dojo part 2: Stretching in the Dojo

Following on from Part 1 , I wanted to make an interactive way to explore the mechanics of string bending. A spreadsheet is the simplest way to do that, but it needs users to download a file and open it up with the right program. A web-app only needs a browser and internet access to use, but takes a bit more assembly. To cut down the amount of DIY needed it's common to use a framework . JQuery is probably the most commonly used, but without built-in support for plots, so I went for the slight more complex Dojo . I tried to make the maths background in Part 1 understandable for a general audience, but this Dojo section is going to have to assume you know a few programming terms. If that doesn't sound like your thing, then maybe you're just looking for the string bend calculator .
