Learn a new Ukulele chord every day of the year. The chord for February 8th is Gmaj7
Harmonic Function for: Gmaj7
The Harmonic Function of a chord is simply how a chord is being used in a harmonic context with other chords in a song or chord progression.
Here are the most common harmonic functions for today's chord.
Gmaj7 is a Full Diatonic , primary chord in the common Major key(s) of: G (I) and D (IV)
Gmaj7 is a Full Diatonic , primary chord in the common Minor key(s) of: Dm (VI) and Gm (III)
Harmonic Analysis, Scales, and Modes
All harmonic and scale analysis utilizes Roman Numerals related to the major of the current tonality (key) ( I II III IV V VI VII , the 1 2 3 4 5 6 7 of the major scale).
Technically, the modes are numbered the same ( I II III IV V VI VII , the 1 2 3 4 5 6 7 of the major scale) but for comparison they can be numbered relative to the major scale of the same root. Example: C Mixolydian mode ( I II III IV V bVII VII , the 1 2 3 4 5 6 b7 ).
Naming Chords
Today's chord might also be called Em9 and/or — the list can go on and on with more and more obscure chords. It all depends on the harmonic situation and the chord's harmonic function that it is being used in that determines the name of the chord. A bass player can change the function of a chord with the bass note they play, as that can be perceived as the root or letter name of the chord. Bass players have extreme harmonic powers, and they can use it for good or evil.
What's really useful is you don't have to learn a new fingering or voicing for other same shape chords when they come up. If you recognize the chord as another chord that is common in your repertoire, you can re-use it in the current context.
Anything Goes…
Here is a cool, fun exercise: *7alt —alt
, short for
alteration. This is telling you that you are free to create the seventh chord with any
upper partial extension (9th, 11th, 13th) and any alteration(s) that you would like:
♭9, ♯9, ♯11, ♭5, ♯5, ♭13. An example would be
C7alt, the base C7 is C E G Bb – the
1 3 5 ♭7. You're free to add D♭, D♯, F♯, G♭, G♯, A♭.
So your possible notes available are: C D♭ D D♯ E F F♯ G♭ G G♯
A♭ B♭. Notice B, the major seventh is NOT available. So, bottom-line is
— if your chord does not contain a major seventh, you can justify every other note you
are playing.
So when it comes to that dominant seventh chord or tri-tone sub resolving to what would be its I chord — if you don't know what to play, grab any shape and go for it. You have a 1 in 12 shot of hitting that major seventh, which would be really hard to justify a B7alt — B is the major seventh.
Including the 3rd and b7 goes a long way in keeping the intent of the base 7th chord. So you have two more notes to work with — BUT NOT the major seventh. Walk over to any piano and play those two white keys together, and you get the why.

Chord Type(s): Major 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. 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
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 Put your finger here…
, in Standard Music Notation
, TAB
, and in text, graphically using a Chord Grid
, etc.
Derived From
Today's chord, Gmaj7 is a derived chord from G . Take any chord progression with G in it and explore substituting Gmaj7 for G.
Chord Spelling
Chord Spelling is simply knowing what the notes, the chord tones of a chord are.

G B D F#
The chord tones are the 1 3 5 7 scale degrees of the parent G Major Scale .
Recommended Fingering(s)
Although 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 Gmaj7 is:
Recommended Fingering
0 1-1-1
Alternate Fingering(s)
Here are a few alternate fingerings for today’s Gmaj7 chord depending on the context the chord is being used.
Alternate fingering(s) for Gmaj7:
- - 0 2 3 4
- - 0 2 2 3 - A finger stwo barre across strings three and two. This is the same alternate fingers and the open position D chord.
- - 0 3-3-3 - Good preparation for movable chords.
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 musical situations where you might use your thumb but they are 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 Gmaj7 are: G B D F#
Gmaj7 is the 1 3 5 7 of the G Major Scale based on the root (G) of the chord.
Major Seventh Chords, maj7
A major 7 chord is created by raising the flat seven of a seventh chord one fret.
A major 7 can also be created from a major triad by lowering the root one fret.
Next Steps
After memorizing today's Gmaj7 chord and when you are 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.
