A while back I blogged about music theory for geeks and got a lot of feedback from my fellow musicians (some geek some not). Then I blogged for over a month about a new technology named Dojo Toolkit, which essentially is a JavaScript toolkit to create really cool looking AJAX/Web 2.0 applications. As a pet [...]

About 6 weeks ago I started a pet project to experiment with Dojo Toolkit which I tentatively called Musician’s Friend. My goal was to see whether this technology is really mature and stable enough to be used in an enterprise grade software project, and to create an application that might one day [...] I was hoping to wrap up our mini application this week and move on to another project. Then I suddenly realised that the application stopped working for Microsoft Internet Explorer (IE) after version 3. I pretty much spent my entire spare time trying to debug the problem with not much traction so far. Documenting failures [...] This week I’ll complete the chord and scale definitions and add some functionality to the application. There is a large number of chords, most of which I believe is now included in our application. I omitted some rarely used chords which spread out to two octaves. Also note that some added notes, such as ninths, elevenths, [...] I left it where we had a simple GUI that didn’t do much last week. This time I’ll try to implement a simple, but working version of our little Musician’s Helper application. My primary design goal is to make this really intuitive and useful for a musician who wants to figure out or practice [...] I’ll continue to develop our application I’ve started last week by refining the layout of the user interface and continue adding more features to it. First thing I’ll do is to add the keys and scales under the Accordion Panels named Keys and Scales. Here I’ll try to introduce another cool visual feature of Dojo framework, [...] If you have ever attempted to write software that has a GUI (Graphical User Interface), you’ve probably noticed that creating both intuitive and functional user interface is a lot harder than it looks. A number of different skills are required to design a good user interface, skills often hard to find in one [...] Last time I went through the chromatic and major scales. Today I’ll put the chromatic scale on a circle and create a pretty handy gadget, a low-tech computer to figure chords and scales out. In fact I will create two circles, which we’ll attach together later. The first circle is for the “degrees”, and it will [...] Now that we know what a musical note refers to, we can move on with some other basic concepts. At the end of the day, all music theory is based on the 12 notes in an octave. So once you understand how each note is related to others, the same principles hold for other octaves [...] Music theory is hard to learn for most people. It involves a lot of abstractions at many different levels, such as notes, scales, chords, progressions, inversions, etc. It takes years to assimilate all of this information, and even more before you can actually put them to practical use. I’ve always thought that the standard learning [...] |
