<p>I came across an interesting article at [Twelve-Tone</a> Musical Scale](<a href=“http://thinkzone.wlonk.com/Music/12Tone.htm]Twelve-Tone”>Twelve-Tone Musical Scale) that I thought some of the folks on this site might enjoy.</p>

<p>I think my brain just exploded. :)</p>

<p>I think my H will enjoy it, though.</p>

<p>fascinating!</p>

<p>I have started practising the piano a lot lately. And yes equal temperament does sound out of tune now. It feels v odd.</p>
