Fractional Harmonic Metronome Intro - Screen Shot - What it sounds like - More about the golden ratio rhythm - Combining more rhythms like this Intro skip With this metronome you can play rhythms involving fractions or irrational numbers like the golden ratio. So far that's like the Fractional Rhythms metronome. The new thing is, you can also play them with musical pitch intervals using the same fractions or irrational numbers for the musical intervals, like the Harmonic metronome. So it brings together the ideas in both of those metronomes. So for example, PI / 4 will be played using two pitches at a ratio of PI to 4. As with the Fractional Rhythms metronome, the beats drift out of phase with the bar lines.

As with the Basic Metronome, you can accent or unaccent beats with RIGHT CLICK, skip beats with LEFT CLICK, adjust beat volumes with MIDDLE CLICK or SHIFT + LEFT CLICK. For details see the page about the Basic metronome.

You can also play your rhythm with a gradually changing tempo, or add a lilt to the bar timings. For more about this see the page about the Pro metronome.

What it sounds like

Here is what it sounds like: Harmonic Metronome golden ratio / 4

The golden ratio rhythm is in a sense the most polyrhythmic possible rhythm, and the golden ratio pitch interval is the most inharmonic possible pitch interval. So if you asked two musicians to play as far out of tune with each other as possible, and also to play steady rhythms as far out of time with each other as possible, then in a certain well defined sense, this is what they should play. It is so far out of tune and out of time that it sounds really good! Like a meeting of two completely different realms :-).

More about the golden ratio rhythm

skip - skip back

Although the golden ratio rhythm is as inharmonic as you can get, i.e. as far as you can get from a harmonic series based interval - it is a pleasant musical interval actually on most instruments. Some inharmonic pitch intervals are very pleasant sounding. The intervals that are most often hardest on the ear are ones close to a very pure interval such as a fifth, octave or fourth, but obviously not hitting it, such as the detuned "wolf fifths" (though this is timbre dependent).

So anyway, the golden ratio rhythm preset for this metronome gives the most polyrhythmic possible rhythm combined with the most inharmonic possible interval.

For an introduction to the golden ratio rhythm see the Fractional Rhythms Metronome.

You can also combine more rhythms in the same way, each part as far out of time and out of tune (i.e. out of tune in the harmonic sense) with the previous part as possible:

Here is what it sounds like: Harmonic Metronome golden ratio with g squared and g cubed / 4

Of course you can also make rhythms at other musical intervals such as PI / 4 etc.
