110Hz_minus5.flac

I sicked Paulstretch at the lovely chimes from VSCO https://freesound.org/people/Samulis/sounds/375630/ then turned it into something with a more harmonic timbre with a fundamental of 110 Hz, picking a small piece to render. Then I edited the sample to get rid of 5th, 10th, 15th, 20th and some more harmonics.

Using this timbre, one should be able to make septimal thirds (9/7 major and 7/6 minor) sound more consonant by subtracting dissonance peaks around the usual (pental) thirds (6/5 minor, 5/4 major), which should be constituted by harmonics 5n. Other intervals close to intervals with 5 in their ratios should sound a bit more consonant too (e. g. usual sixths: 8/5 minor and 5/3 major).

I haven’t experimented yet but I assure you. :D

(There is another sound in this pack which almost lacks some lower 3rd harmonic multiples. This should allow you being close to harmonies without fifths and fourths (3/2 and 4/3 resp.), e. g. maybe making the septimal tritone 7/5 to sound better.)

Also one should probably take a sampled instrument and process all its samples with a notch filter, or a comb filter, or FFT or something else, to make a timbre with good usability. This one is just an example I want to share, which may accidentally work for something.
