I’d welcome someone to come out and test the accuracy of the metronomes with an oscilloscope or a nuclear clock…but for now, I’ll stick with these results. And the two guitar programs seemed to run slow at 60 bpm and faster at 120 bpm. Two applications, Maestro and Metron seemed to run consistently fast. Subdivide Metronome was accurate at 60 bpm, but I was unable to set the metronome to 120 bpm (119, yes, 121, yes, but it would skip 120). Betotte TC, Metronome Pro, Tempo, and Tempo 2 seemed to run accurately with my watch. I took my Fossil watch, and examined the tempo of each application at 60 bpm and 120 bpm. I had no scientific method to test the accuracy of these metronome program. Many of these apps have additional features which I am not going to comment on at this time–you can do some further research at the App Store, or by contacting the developers, if you would like to learn more about those features on specific apps. Nearly every metronome application offers an in-app instruction manual (you’ll need it with Metron, for example), or offers instructions (if necessary) online. For the record, Maestro, Metron, Metronome Pro, and Subdivide Metronome gave me promo codes so I could review their programs. Betotte TC, Gibson Learn and Master Guitar, Guitar Toolkit, Maestro, Metron, Metronome Pro, Subdivide Metronome, Tempo, and Tempo 2. The apps that will be mentioned in this blog post are: Dr. Chances are that you will buy more than one of these programs. Depending on your needs and interests, you should carefully choose the metronome that works best for you. For example, some metronomes are better at simply giving a beat and holding to that tempo, others are better for programming a beat track for an entire composition. Each app takes its own approach, and none is an all-stop shop. It would be nearly impossible to review all 150 metronome apps therefore, there are nine applications on my iPhone which cover the variety metronome apps you will find on the AppStore. Some programs, such as Tempo, have multiple versions. In fact, a search of “Metronome” in the AppStore yielded nearly 150 programs. Therefore, a metronome is a necessity for the musician–and that tool is readily available on the iPhone/iPod Touch in a variety of formats. And the core of rhythm is the sense of beat.

The late, great Robert Shaw taught that rhythm was music. John Cage demonstrated that organized time even makes unorganized sound into music. Rhythm is at the very core of what music is without defined time, music becomes unorganized sound. There is, perhaps, no more basic tool for the musician than a metronome.
