Understanding Chord Movements
Another thing I wanted to tell you about making chords is this: once you've got that shape down, to play in other keys, you just move the chord up and down as needed.
Importance of Knowing Scale Notes
It helps to know the notes of a scale, and this information will also be available on the website. Here are the notes:
- G
- G sharp
- A
- A sharp
- B
- C
- C sharp
- D
- D sharp
- E
- F
- F sharp
- G
Changing Keys: Example with A and B
Let's say you're in the key of A, and the singer says, "Ah, that's too low for me. I want to sing it in B."
To adjust, you'll need to:
- Identify the A note.
- Locate the B note:
- It goes: A, A sharp, B.
- The distance from A to B is two frets (1, 2).
This means you need to move your chord up two frets to play in B.
Visual Representation
Actually, this will be easier to understand with a visual representation, so refer to the diagram if available.
Playing Chords in Bluegrass
Now, regarding the basic major chord used in bluegrass, let's focus on the key of A.
To play a D chord from A:
- Keep the shape you see in A with your three fingers in their relative positions.
- Move it up in the direction needed.
If you don't have a place to put a finger:
- You generally don't want to play the open E, as it won't sound good in a bluegrass context. Instead, just play the bottom three notes.
Playing All Four Strings
If you want to play all four strings, take the D note and switch your finger positions.
- Use your bottom three fingers instead of the initial three.
- This gives you the same notes but allows for finger flexibility.
Now you can fret the second fret of the E string with the freed finger, enabling you to play all the notes.
Before, if you hit all the notes with the original position, you'd get an E, which is not part of a D or D major chord. The shape with F sharp on top looks like this.
Moving to E Chord
To play an E chord, do the same thing you did for the D chord:
- Move it up two frets.
Quick Chord Changes
A lot of times, when playing some tunes, you'll only need to switch between an A and an E chord.
Instead of going through the process of lifting all fingers, do this:
- Keep a finger planted: This note (E) is common to both the A chord and the E chord.
- Change only the three fingers that are needed.
At first, this switch will be difficult and will require thought. However, with practice, it becomes an economical way of changing chords without lifting everything up.
About the instructor

Tom Bekeny is a mandolinist, fiddler and seasoned mandolin teacher who has performed and taught in the U.S. and abroad for over 40 years - so when he breaks down how to play, you are learning from someone who has spent a lifetime both on stage and in the lesson room. He was the mandolinist in such San Francisco Bay Area bands as Done Gone, Tenbrooks, and an early version of the Grant Street String Band with Laurie Lewis. He has appeared with Peter Rowan, the Rowan Brothers, David Grisman, George Cole, vocalist Lua Hadar, and Jerry Garcia. Tom has played mandolin with the highly acclaimed Kathy Kallick Band for almost 20 years and has held the fiddle spot with California's premiere traditional bluegrass band, High Country, since 1988. He has recorded with many of these groups and was featured in the Summer 2009 issue of Mandolin Magazine. Tom also plays in the wildly popular trad bluegrass "jam" band, Bangers and Grass, alongside west coast bluegrass luminaries Jim Nunally, Steve Pottier, Bill Evans and Chad Manning. Beyond bluegrass, Tom plays jazz mandolin with his trio The Missing Man Quartet (MM4), which plays straight-ahead jazz with original arrangements drawing material from the world of jazz and Great American Songbook standards. He released a solo CD project ("Jazzolin") in 2013, on which he plays mandolin and fiddle backed by drums and bass. read more
