'''[https://soundcloud.com/user-824310486/jolly-ride Jolly Ride]''' is a piece written in the equal-tempered Bohlen-Piercescale (13ed3). Using an eclectic musical language from baroque, jazz/ragtime, and impressionism, I tried to shed light on the possibilities of BP. Using mostly the lambda scale as a base, modulating between different tonalities, I also use False Father with its pseudo-octave at one point. BP is mostly known as a scale with low tension, I found that there is more in it.

Would blues on an other world sound like that? | |||
Tuning recipe: Start with a 9:10:11 chord. Repeat it all over in 7:9 periods. While giving you savvy 7:9:10:11 harmonies, it lacks a clear octave period, forcing you to seemingly polytonal settings. | |||

Experimenting in the neighbourhood of diatonic JI, I found some scales with astonishing similarities in the way they can be build, leading to a whole scale family with low harmonic entropy. | |||
==== Diatonic JI scale ==== | |||
* Start with a 8:9:10 chord. | |||
* Iterate this pattern every 6:8, i.e. 3:4. | |||
* Stop iteration at the octave (2:1). | |||
The scale contains a 6:8:9:10 chord, whose inversion is a (filled) major chord: 8:9:10:12. This pattern occurs twice. The third major chord contains a Pythagorean major third (diapasson). | |||
The resulting scale:<blockquote>! byzantine.scl</blockquote><blockquote>Byzantine Diatonic</blockquote><blockquote>! repeats every 4:3 until iteration stops at the octave.</blockquote><blockquote>7</blockquote><blockquote>!</blockquote><blockquote>9/8</blockquote><blockquote>5/4</blockquote><blockquote>4/3</blockquote><blockquote>3/2</blockquote><blockquote>5/3</blockquote><blockquote>6/9</blockquote><blockquote>2</blockquote>The scale steps are: 9/8, 10/9, 16/15, 9/8, 10/9, 16/15, 9/8. | |||
==== Slendro JI scale ==== | |||
* Start with a 6:7:8 chord. | |||
* Iterate this pattern every 6:4, i.e. 3:2. | |||
* Stop iteration at the octave (2:1) | |||
The pattern contains a 4:6:7:8 chord, which can be interpreted as a 2:3:4 open-fifth chord, which is septimally filled. This pattern occurs once | |||
The resulting scale: | |||
! ji-slendro.scl | |||

7/6 | |||
4/3 | |||
3/2 | |||
7/4 | |||
2 | |||
The scale steps are: 7/6, 8/7, 9/8, 7/6, 8/7 | |||
==== Sweet Nine ==== | |||
* Start with a 10:11:12 chord. | |||
* Iterate this pattern every 10:8, i.e. 5:4. | |||
* Stop iteration at the octave. | |||
The base chord ist 8:10:11:12. | |||
The basic scale steps are 11/10, 12/11 and 25/24. The iteration stops at a 16/15 interval. | |||
The resulting scale: | |||
! sweetnine.scl | |||
Sweet Nine. Based on an 8:10:11:12 chord. | |||

11/10 | |||

==== General pattern ==== | |||
* Choose a chord of 3 following integers, for example 3:4:5 | |||
* Double the numbers, filling the upper gap. Example: 6:8:9:10. This is your base chord. | |||
* Start your scale with the upper triad as your chord. | |||
* Iterate this chord, using the lower dyad as generator. | |||
* Stop iteration at a chosen period interval. Example: 2:1 | |||
