Chord Type(s): Diminished 4-part

Chord Categories: Open Position

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 and are almost entirely learned by shape and sound – hopefully, the chords' name. 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

Standard music notation and TAB for C Tuning, Low and High G variations

The same numbering notation of 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.

Recommended Fingering

LH_fingersAlthough additional fingerings are possible for many chords. Fingering for any given chord depends 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 and 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 diminished seventh is:

Recommended Fingering
0 2 0 3

Alternate Fingering(s)

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 can reach the lower string four and three goes a long way to being efficient when switching chords.

Factors such as playing notes right behind the fret takes less effort than in the middle of the fret. Less effort leads to overall efficiency in play, 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.

Chord Construction, Notes and Intervals

ALL chords can be be constructed based on the 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.
