Naming Chords
Today's chord might also be called Cadd9sus4 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.
Open Position Chords
Today's chord, Cadd9sus4 is an Open Position chord.

Chord Type(s): Major Sus Add
Chord Categories: Open Position Triad
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, Cadd9sus4 is a derived chord from C . Take any chord progression with C in it and explore substituting Cadd9sus4 for C.
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 Cadd9sus4 are:
C F G D
The chord tones are the 1 4 5 9 scale degrees of the parent C 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 Cadd9sus4 is:
Recommended Fingering
0 2 1 3

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 Cadd9sus4 are: C F G D
Cadd9sus4 is the 1 4 5 9 of the C Major Scale based on the root (C) of the chord.
sus or suspended Chords
A sus chord implies the suspension of the third of a major, minor or seventh chord. The most common, historical, and traditional use of this suspension involves raising the third of a major or seventh chord to the fourth for a sus4, or 7sus4. In some contemporary music, the suspension can also be accomplished by lowering the third of a major or minor chord to a second for a sus2 chord.
A sus or suspension displaces the third of a chord. An Am sus4 or Am sus2 would be the same as the sus4 and sus2 chords in lesson one's A major chord.
Because a suspended
chord lacks a third, these chords feel unresolved and often “resolve” back to a standard major or minor chord.
The term is borrowed from the contrapuntal technique of suspension, where a note from a previous chord is carried over to the next chord—suspended into the next harmony, and then resolved down to the third or tonic, suspending a note from the previous chord. However, in modern usage, the term concerns only the notes played at a given time; in a suspended chord, the added tone does not necessarily resolve and is not necessarily prepared (i.e., held over) from the prior chord. A common suspension is a fourth above the root resolving to the third of the chord. Sevenths, ninths, and seconds are also common suspensions.
Technically a sus2 is not really a chord as in traditional harmony a sus or suspension only referred to the third of the chords. So, really a sus2 is most likely a power 5 without a third and with an added 2. And, another chord
that, at its foundation is not a chord but a DYAD.
As tonality expanded, classical composers began embracing less functional harmony structured in fourths and fifths. In popular music, it also became commonplace to leave suspensions in place without resolving them.
In Jazz
A common suspended chord in jazz combines the supertonic and dominant chords into one sonority: V9sus4 . Basically the II V of a II V I is combined. An example in C: the Dm7 G7 is combined as Dm7/G .
add2/add9 Chords
Technically the add 2 and add 9 are different chords.
Both the 2 and the 9 are the same letters but in different octaves of the scale. On ukulele, for all practical purposes, you can treat both the add2 and add9 chords as the same. Depending on whether you are using a low “G” or high “G”, C tuning the added ninth might be a second. Whether you call it an add9 or add2 depends on whether the added note is in the same octave as the root of the chord.
Related to a C Major Scale a D is both a 2nd and a 9th (shown to the right). All depends on where the root is.
