ULCAD0301 Chord_grid_legand.png Understanding a Chord Diagram
Open Position chords typically do not show the location of the root or letter name of the chord, as these chords are the first chords a ukulele player learns. They are almost entirely learned by shape and sound–hopefully, the chord names. Later on, one develops the ability to determine the location of the chord root(s) or letter name within the chord.
Standard Music Notation and TAB
ULCAD0301
Standard music notation and TAB for C Tuning, Low and High G variations
The same numbering notation used in TAB can be used to describe the open strings and frets to be played when using text-only notation or verbal communications. Using an open position C as an example, we can describe it as 0003, indicating open strings four, three, and two with fret (3) being fingered on string one. An open position, D7 , indicated as 2020 .
As you can see that are numerous ways to describe a chord, either verbally, Standard Music Notation , TAB , in text, graphically using a Chord Grid , etc.
Derived From
Today's chord, Bb is a derived chord from A . Take any chord progression with A in it and explore substituting Bb for A.
Chord Spelling
Chord Spelling is simply knowing what the notes, the chord tones of a chord are.
The notes of all chords can be determined from its corresponding major scale based on the root of the chord and numeric formula.
The notes for Bb are:
Bb D F
The chord tones are the 1 3 5 scale degrees of the parent Bb Major Scale .
Additional Information

Bb is a movable version of the open position A with the root on string one and string four. I've only shown the root on string one. You can uses either root for transposition purposes.

Recommended Fingering(s)
LH_fingersAlthough additional fingerings are possible for many chords, fingering for any given chord depends on the science of how our fingers work and on the harmonic context the chord is being used in—what was the previous chord, and what's the next chord? The goal is to play all the notes right behind the frets when possible. Remember, longer fingers can reach the lower strings better, and finger two can stack on finger three, and finger three can stack on finger four.
Although you can play any chord with any finger as long as it's yours, the recommended fingering for Bb is:
Recommended Fingering
3 2 1-1
Alternate Fingering(s)
Here are a few alternate fingerings for today’s Bb chord depending on the context the chord is being used.
Alternate fingering(s) for Bb:
  • A barre across strings one and two is the most efficient finger for this chord. DO NOT barre more strings than necessary unless there's an overwhelming musical reason for the barre. An example when quickly switching between todays chords and tomorrow's Bb7 in a very fast rhythmic pattern.
Fingering Notation
Fingering notation for a chord using text only, without using a chord grid, is typically done using the finger numbers from left to right, string four to string one (nose to toes). Here is the text notation for January 1st C chord.
A Typical text representation of a chord fingering without using a chord grid.
Note: A Zero (0) fingering notation represents an open string that doesn't require using a finger.
Fingering Chords
Additional alternate fingerings might be possible for selected chords. If there isn't an overwhelming musical reason for one fingering over another, let efficiency be the determining factor. Something as simple as longer fingers that can reach the lower strings four and three will go a long way to being efficient when switching chords.
Factors such as playing notes right behind the fret take less effort than in the middle of the fret. Less effort leads to overall efficiency; lower maintenance for maintaining your technique and efficiency leads to speed. This can help in determining what finger to use. Finger three can overlap finger four, and finger two can overlap finger three a little, allowing them to get closer to the fret.
Remember, the thumb's primary role is to support the fingers–not play notes. Think of the thumb as a Stagehand. He is unseen, doesn't get any lines, but is a critical member of the team. There are musicial situations where you might use your thumb but they mainly rhythmic / strumming reasons.
Chord Construction, Notes and Intervals
All chords can be constructed based on their intervals relative to the major scale of the root or letter name of the chord. The individual names of the notes of the chord can also be determined from the same scale.
The chord tones for Bb are: Bb D F
Bb is the 1 3 5 of the Bb Major Scale based on the root (Bb) of the chord.
Next Steps
After memorizing today's Bb chord and when you able able to switch in time with other chords. The next step is adding various Strums , Fingerpicking patterns, and exploring the Movable Chord versions of today's chord, to your ukulele skills.
