One pitch, more than one place
A written note usually has one obvious place in first position — but not always. When it has more than one, this course gives you the beginner default and tells you it's a choice.
The same-pitch checks
Your 4th finger reaches the pitch of the next open string up — exactly:
| 4th finger on… | = open string |
|---|---|
| G string, 4th finger | open D |
| D string, 4th finger | open A |
| A string, 4th finger | open E |
Play the 4th-finger note, then the open string. In tune, they're identical — the same pitch, two ways to reach it. This is a free tuning check for the 4th finger, on every string.
Two notes, each with two homes
Which one do you play?
Mostly the one that avoids a string crossing. If a phrase is sitting on the A string and touches an E, the open E keeps you there — no need to cross to the E string for one note. Later, tone and phrasing change the answer; for now, stay on the string you're on.
The usual mistake — the octave trap
The 4th finger on the G string is open D — the D just above the low open G, a fourth up. It is not another low G. And the 3rd finger on the D string is G, but the G an octave above the open G string — a completely different pitch. Same letter, different octave: check the staff position, not just the name.
Try
Play these pairs and listen for them to become one sound: G-string 4 ↔ open D · D-string 4 ↔ open A · A-string 4 ↔ open E. Then play D-string 3rd-finger G and open G — hear that they're an octave apart, not the same.
