I was assigned a Bach piece to play and was told that certain sections should be in open, 5th or 7th position. I am only a few lessons into my training and I don't really understand yet what these mean and most of my fretboard understanding is in the open position. How should I approach this?
This may help. It is a cut and paste from a post on the getting started string. Look at how the notes fall in open 5 and 7 position.
For this paper we will be referring to notes as A, B, C & 1, 2, 3. For example:
C Major Scale…….....…C, D, E, F, G, A, B, C (octave)
Scale degree number. 1. 2, 3,.4,.5, 6, 7, 8 (octave)
The Major Scale Box Pattern will also be used in our examples.
The Major Scale Box
G|~~|---A----|-------|---B---|---C---|1st string
D|~~|---E----|---F---|--------|--G----|
A|~~|---B----|---C---|-------|---D----|
E|~~|---------|---G---|-------|---A----| 4th string
C and D played on the A string.
E, F and G played on the D string.
A, B and C played on the G string.
Why did I place the C root note on the A string? If we place the tonic root note of the scale or chord progression on the A string the 4th and 5th scale degrees will be above and below the tonic root note. Why is that important? The I-IV-V chord progression finds its way into hundreds of simple songs. Having the I, IV and V root notes all together in one spot will prove to be an advantage.
Now to that 5th and 7th thing...
5th fret rule
The A at the 5th fret is the same as the open A string.
The D at the 5th fret is the same as the open D string.
The G at the 5th fret is the same as the open G string.
7th fret rule
E at the 7th fret is the same as the E open string.
A at the 7th fret is the same as the A open string.
D at the 7th fret is the same as the D open string.
Finding the other notes
- From any note where is its 2? Over two frets same string.
- From any note where is its 3? Up a string and back one fret.
- From any note where is its 4? Up a string same fret.
- From any note where is its 5? Up a string and over two frets, or right below on the next string down, same fret.
- From any note where is its 6? Up two strings and back one fret. Right over the 3.
- From any note where is its 7? Up two strings and over one fret. If you want C’s 7th find a C and the 7th is back one fret. This comes in handy when moving back down a scale.
- From any note where is its 8? Up two strings and over two frets.
Hope this helped.
