harmonic theory VII

accord notation

Popular is the following,
The first thrid within the accord tells if its a minor or a major accord. Is nothing told a major third is expected. (major means great-third C-E, minor means small.third C-Eb).
The fifth is obligate and does not need to be noticed if its not clean (clean means 7-half-steps).
The seventh means the small seventh (C-Bb). If the big seventh is used like in C maj7 the "7" needs the attribut "maj" to show that the big seventh is used (C-B instead of C-Bb).
Same ges for intervals above the octace. the nine menas the big nine a whole ton above base tone. (C-D). Aberant use of the small nine will be notated as "b9". The eleventh by default means the clean 11 (C-F) and the 6th allso the big by default (C-A). Aberant uses will notate like "#11", "b11" or "b6".

The following notation is popular:

CDbDEbEFF#GG#ABbB
1b99#9/b334#4/b55b6/#567#7(maj7)

The higest notated intervall includes all lower thrids.
On major 7 accords ( dominant-seven ) and includet clean quart will be outmitted.
Sus-accords stands for suspendet. Instead of the first third a suspendet tone will be used.
On add-accords (add for addition) will the interval be addet to the accord.
