This article focuses on a systematic approach to building '''overtone scales''' (modes of the harmonic series), with attention paid to the different kinds of relationships available depending on the starting pitch, or tonic notes.  
An '''overtone scale''' is a [[scale]] made from an octave-spanning segment of the [[harmonic series]], repeated at the octave. Overtone scales are also called '''modes of the harmonic series'''. Their inverses, made from the [[subharmonic series]], are '''undertone scales'''.

It is not concerned with "purity", "consonance", "naturalness" or avoidance of "dissonance". Here, what might be called dissonant is instead called complex, and the reader is encouraged to explore the sounds of harmonic ratios ranging from the simplest to the most complex. This does not mean that the more complex intervals can be treated exactly the same way as the simpler ones, but that different levels of complexity can be valuable to explore in a tuning system. The usefulness of all this is left to each composer to determine through experimentation.

; [[8afdo|Mode 8]]: 8:9:10:11:12:13:14:15:16 – an [[octatonic|eight-tone]] scale, or a [[13-limit]] [[octad]].

[[Dante Rosati]] calls it the "Diatonic Harmonic Series Scale" and has refretted a guitar to play it. See: [[First Five Octaves of the Harmonic Series]] and [[otones8-16]].

It includes a [[19-limit]] minor chord, 16:19:24, in addition the the classic major. Incorporating harmonics through the 31st, a great variety in complexity is possible. As 16 is a lot of tones to use at once, this is a good scale for making modal subsets of. Andrew Heathwaite recommends his heptatonic "remem" scale – 16:17:18:21:24:26:28:32 – or his extended nonatonic "remem" scale which adds 19 and 23 – 16:17:18:19:21:23:24:26:28:32.

Over-1 scales have a very strong attraction to their tonic, which is the fundamental of the series. Other Over-''n'' scales may have more complex relationships to their tonics, which are not fundamentals. Indeed, when taking subsets, the fundamental may not even be present.

Mode 30 in particular is interesting because 30 is the product of the first three primes, so it is a fairly good choice if we want a tonic that is not a power of two. It contains modes 6 and 10 as subsets. We have the classic minor triad (from 10), the subminor triad (from 6), two major triads in 30:37:45 and 30:38:45, and the Barbados triad of 30:39:45. Chords not based on the tonic include the harmonic seventh chord (32:40:48:56). A good 13-limit subset with 16 notes in it is 30:32:33:35:36:39:40:42:44:45:48:49:50:54:55:56:60.

* Go beyond the 24th harmonic, for example with the segments [[Harmonics 16–32|16::32]], [[Harmonics 32–64|32::64]] or [[Harmonics 128–256|128::256]].
Here are some next steps:
 
* Go beyond the 24th harmonic (eg. harmonics 16-32 or higher).
* Experiment with using different pitches as the "tonic" of the scale (eg. '''sol lu ta do re mi fu sol''', which could be taken as the 7-note scale starting on '''sol''').
* Experiment with using different pitches as the "tonic" of the scale (eg. '''sol lu ta do re mi fu sol''', which could be taken as the 7-note scale starting on '''sol''').
* Take subsets of larger scales, which are not strict adjacent overtone scales (eg. '''do re fe sol ta do''').
* Take subsets of larger scales, which are not strict adjacent overtone scales (eg. '''do re fe sol ta do'''). The 12-note [[Carlos harmonic scale]], a subset of 16::32, is a well-known example; see also [[ringer scale]]s.
* Learn the inversions of these scales, which would be [[IFDO|undertone scales]]. (Undertone scales would have smaller steps at the bottom of the scale, which would get larger as one ascends.)
* Learn the inversions of these scales, the undertone scales, which are built from the [[subharmonic series]] (see [[Subharmonics 16–32|subharmonics 16–32]]). Undertone scales have smaller steps at the bottom of the scale, which get larger as one ascends.
* Borrow overtones & undertones from the overtones & undertones of the fundamental -- this process can produce rich fields of interlocking harmonic series, and is often the sort of thing that composers do when they're composing in just intonation. [[Harry Partch]]'s "Monophonic Fabric," which consists of 43 unequal tones per octave, is one famous example.
