Re: Spreadsheet for calculating chord frequencies *REVISED*

So, what conclusions can you draw from this table? Well, first of all, the 3 lower notes cause a major triad: root, major third and fifth. They sound very sweet together; they are a base in all Western music. All intervals are consonances. There are several frequency coincidences between these three...

Re: Spreadsheet for calculating chord frequencies *REVISED*

Update: Changed the base frequency to 100 (from 440) for easier reading. Let's look at the frequencies of the notes involved in the tetrad 4:5:6:7 discussed above. Here is a table with the example frequencies 100, 125, 150 and 175 Hz. Each note has a fundamental (e.g. 100 Hz). This note has overtone...

Re: Spreadsheet for calculating chord frequencies *REVISED*

Anyone interested in chords and frequencies mathematics, harmonics, etc. should read this article: https://en.wikipedia.org/wiki/Harmonic Here I will present a table, that is similar to one found in the above mentioned article, but here it will show what notes are actually contained in a single note...

Re: Spreadsheet for calculating chord frequencies *REVISED*

Quite clearly in my opinion, the best sounding tetrad of the above is the one where the frequencies are related 4:5:6:7. These are pretty small numbers, which make the harmonics smooth. But look at the end of this discussion for the reason why I think this chord sounds so nice. From the root to the ...

Re: Table of reedplate dimensions? *REVISED*

OK, I measured a few harps at home, and here are the results. I included photos of the disassembled harps on top of a millimeter grid paper (mm hardly visible, cm clearly visible). Could be useful for finding placements of screwholes, cut-outs, rounded corners, or whatever. This is just a test and a...

Re: Table of reedplate dimensions?

Interesting question. I could measure a few reedplates I have at home and post here when I have the time. Would be interesting to see which are interchangable.

Cheers, Karl

Re: links to lyrics and notes in the www

There is one link up there (well, 2 actually...) leading to a site http://gada.se/, which contains stuff from a band of "Gammaldans" (Swedish/Nordic for "Old Dance", ie. traditional dance tunes, usually performed on fiddle and/or accordion). (https://en.wikipedia.org/wiki/Gammaldans) That gada.se si...
