Guitar Tuner Widget

Guitar Tuner Widget is a very small tool that gets built into Yahoo! Widget Engine and lets you play a virtual guitar right on your screen. It is easy to install and set up.
The frame of the widget can be moved to any position on the screen, with the help of the mouse cursor. All you have to do is hover the cursor over any string, and the widget automatically generates the tone corresponding to the respective scale.
By opening the context menu, you can bring up the Widget Preferences panel and switch from standard mode to Drop D tuning. There are no other options provided by Guitar Tuner Widget.
However, thanks to the settings supplied by Yahoo! Widget Engine by default, you can set the frame to stay on top or below all the other frames, to ignore mouse events and to prevent dragging. Plus, you can set its opacity level to a preset value, ranging from 20% to 100%.
Guitar Tuner Widget is very low-demanding when it comes to the CPU and system memory, thus it doesn't burden the computer's performance. It has a good response time and works smoothly, without making the OS hang, crash or pop up error dialogs. All in all, Guitar Tuner Widget should please all guitar enthusiasts who would like to play notes in a virtual environment on the desktop.
