The 3 E’s: Low, Middle, and High
To Know → High E = Space 4 = 1 string open & Low E = -4 Space = 6 string open.
From Middle E [the bottom line]: when we go up 4 spaces from the first line, we have the High E (1st string open). The High E can also be called the top space or 4S [4th space].
From Middle E: when we go down 4 spaces from the first line, we have another E note, the Low E (6th string open). We call this low e…-4 space [minus 4 space]. The Low E is the lowest tone on the guitar in standard tuning.
The 3 E’s are octaves to one another (they are even intervals [8’s] = Space to Line & Line to Space). Low-Middle-High E = Space-Line-Space. Important!
Another interesting way to view the Low E is that if we were to add a vertical line to its ledger lines, we would have a big E.
