### 5/5 — A great reference sheet, all the power is sub-5kHz!

*2022-08-18*

So I shouldn’t be surprised that the infamous range 20Hz to 20kHz is way wider than the fundamentals.  I knew that.  Yet, this is a useful reminder, of just how important the upper range where the harmonics reside is, and that the Fundamental Frequency of notes on our musical scale, that well-known ‘standard’ instruments play, is nowhere near those giddy limits.  So, I just appreciate the listing, it actually made me search for the note frequencies elsewhere, to check it - surely for example, C4 the infamous ‘middle C’ is not wallowing down there at 261.63Hz?  But it is, I wiki-checked it!

### 5/5 — Nice app
