Billion Chords is a software utility that was developed specifically to aid people in accessing a long list of chord combination structures, with a minimal amount of effort.
You are not required to go through the setup process, as this product is portable. This means that the Windows registry is not going to be updated with nay new entries, unless you first approve of it.
Another noteworthy aspect is that it is possible to take Billion Chords anywhere with you, by simply moving the program files to a USB flash drive and running the executable.
As stated above, this tool comes packed with a very impressive list of chord combinations, so that you can learn and practice them. They range from simple to basically impossible, and you can view their graphical representation, as well as the exact chords you have to play on a virtual guitar fingerboard, so that you can be sure you understand the combination.
The moment you select a chord combo, you can hear the way it should sound. Aside from that, you should know it is possible to display all these items for the left-hand chords, use a standard tuning or choose another one from a drop-down menu, adjust the tempo, and toggle between an electric or classical guitar, with just a click of the button.
It does not require many system resources in order to function properly, which means that the computer’s performance is not going to be hampered. The response time is good, the interface is highly intuitive and there are sufficient items to help you learn the guitar in no time.
All things considered, we can safely say Billion Chords is a pretty simple, yet efficient piece of software, which did not pop any errors, hang or freeze in our tests.
