Ordered Lists

admin · May 19, 2018, 7:14 p.m.
Ordered Lists are a useful tool in information processing. Unordered lists are just a grouping of things without the order in the list having any sort of meaning, rhyme or reason. Ordered lists note an ordinal relationship between things in the list. One can order ordered lists in ascending or descending orders or can utilize a foreign key to order the items in some different manner. For our purposes ordered lists help us understand the underlying order of different concepts. For our purposes three important lists are fundamental to understanding the guitar. The three ordered lists are notes, intervals and the Circle of 4ths/5ths. Ordering intervals and notes help us understand how to navigate the fret board going up and down it. The circle of 4ths/5ths help us navigate the fret board going across it. As this course develops other ordered lists may be utilized.

All Notes

The first ordered list we will discuss is all the notes. This ordered list will help us understand how the notes change as we ascend or descend in tone. All the notes we will use are A, A#/Bb. B, C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab, and back to A. When we play in different keys and modes then the entire ordered list is not used instead a subset of the ordered list of notes is utilized. The / denotes that the note in reference can be seen as either a # or a b (flat), depending on the key and mode in reference. Thus sometimes we might be saying D#, and at other times calling the exact same note Eb. There are only 12 notes for the guitar, though if the fret spacing were changed a different number of notes in the system might result.

All Intervals

The second ordered list we will discuss is all the intervals. This ordered list will help us understand how the intervals change as we ascend or descend in tone. All the intervals we will use are 1,b2, b3, 3, 4, b5, 5, b6, 6, b7, 7 and back to 1. When we play in different keys and modes then the entire ordered list is not used instead a subset of the ordered list of intervals is utilized. There are only 12 intervals for the guitar, though if the fret spacing were changed a different number of intervals in the system might result. The interval perspective, like the note perspective helps us navigate the fret board going up and down it. Intervals help us create an underlying structure that will help with playing the modes and various other scales—while helping reduce the total amount of information.

Circle of 4ths

The third ordered list is the Circle of 4ths. The Circle of 4ths/5ths helps us navigate the fret board going across it. The Circle of 5ths is just the Circle of 4th’s in reverse and is that way because of how the guitar is tuned when in standard tuning. From the interval perspective, the Circle of 4ths is 1, 4, b7, b3, b6, b2, b5, 7, 3, 6, 2, 5, 1. From the note perspective, the Circle of 4ths is A, D, G, C, F, A#/Bb, D#/Eb, G#/Ab, C#/Db, F#/Gb, B, E. As we will see later in these lessons, the Circle of 4ths gives us a trick to memorizing the modes. Once someone has these three ordered lists memorized they have a really good conceptual understanding of what is a guitar—at least is a guitar in standard tuning.

Taxonomies

Taxonomies are nothing more than classification schemes that can be deployed to help one advance their goals subject to their constraints. For this course the three major taxonomies that will be deployed are the Beginner Taxonomy, the Information, Hierarchy, Taxonomy, and the Efficiency Taxonomy. These three taxonomies will help the user choose and filter through the different information available in this course. The different taxonomies help Beginners with little to no musical background, or people trying to see what this course is all about and how the different lesson areas relate to one another and the system as a whole and for those trying to become a juke box hero level of guitar player as fast as possible. Selecting the right taxonomy can help minimize frustration with chugging through things that might otherwise be irrelevant to the user. More taxonomies may develop as this course continues.
