Here I present: Guido of Arezzo (991 – 1033 AD), “Micrologus”, 1026 which was a treatise for teaching the singing of chants. Guido of Arezzo is known for teaching singing. “Solfege” syllables of do, re, mi, fa, sol, la, ti, do define a “diatonic” octave. Solfege syllables of a “chromatic” octave are shown ABOVE and BELOW.
The names of the interval between tones is given BELOW. 
0. Unison
1. minor 2nd (half-step)
2. major 2nd (whole-step)
3. minor 2nd (sesquitone)
4. major 2nd
5. fourth
6. tritone
7. Fifth
8. minor 6th
9. major 6th
10. minor 7th
11. major 7th
12. octave
The “major” scale is in the key of C: cdefgabc; and, any arbitrary key WWWHWWH defines the “major” scale (W is whole-step & H is half-step). The “major” scale in C is just the white-keys of piano. The “minor” scale is seven (5) notes of key C# starting on this black-key of the piano. The “minor” scale in key C# is: c# d# e f# g# a b c#; any arbitrary key WHWWHWW defines the “minor” scale.
Here I presented: Guido of Arezzo (991 – 1033 AD), “Micrologus”, 1026 which was a treatise for teaching the singing of chants. The ABOVE table shows the method of “tuning” referred to as “Just Intonation”. Just intonation represented the octave tones as whole number fractions for frequencies.
C 1/1 do
C# 16/15 di
D 9/8 re
D# 6/5 ri
E 5/4 mi
F 4/3 fa
F# 7/5 fi
G 3/2 sol
G# 8/5 si
A 5/3 la
A# 15/9 li
B 15/8 ti
C 2/1 do
Lyrics are syllables of a language; and, lyrics are not nonsense, solfege syllables. A melody and lyrics are combined to create a song. Guido of Arezzo was the first person in history to teach “musico-linguistic” concepts as a simple singing treatise. Singing is controlling how you double pitch to reach an octave of tones with voice.
- When the “major” chord is the harmony, your music perception is the numbers: 8_10_12.
When the “minor” chord is the harmony, your music perception is the numbers: 10_12_15.
