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

ULCAD0331

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.

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 C13#9 are:

C E G Bb D (F) A

The chord tones are the 1 3 5 b7 #99 (11) 13 scale degrees of the parent C Major Scale .

Bb is a movable chord based on the open position A major chord.

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 C13#9 is:

Recommended Fingering
1 2 3 4

Alternate Fingering(s)

Although alternate fingerings might be possible, the recommend fingering for any chord should be based on an efficient fingering, easy to reproduce on demand and Low Maintenance

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.

The chord tones for C13#9 are: C E G Bb D (F) A

C13#9 is the 1 3 5 b7 #99 (11) 13 of the C Major Scale based on the root (C) of the chord.

7th (pronounced Seventh)

A partial seventh chord can be created by lowering the Root of a major triad two frets.

A seventh chord as a 4-part chord ( 1 3 5 b7 ) and one of the Big Six core chords used to derive other contemporary and jazz chords.

A Seventh chord along with your basic major and minor chords are the msot common chord you will encounter.

NOTE: A Seventh chord is very often referred to as a Dominant Seventh . This is not always accurate as Dominant — is a chord function and not actually part of a chord name, which is a capital letter and chord type information – not it's harmonic function. We don't call a seventh functioning as a I (one) chord in a Blues a Tonic Seventh or the IV (four) chord a Sub-Dominant Seventh chord, etc...

Altered Ninths

Altered ninths typically only apply to seventh chords.

An altered nine chord is created by raising the root of a seventh chord one fret for a 7b9 or three frets for a 7#9. Alternate notations include 7-9 and 7+9

13th Chords

13th chords apply to seventh chords (1 3 5 b7). A 13th chords it technically a 7-part chords. The 1 3 5 b7 9 11 and 13 of a major scale. The ninth is a common optional chord tone . The eleventh, optional as well but not as common.

To get this voicing start with a basic 7th chords and raise the root to the ninth and raise the fifth to the thirteenth.

A really cool voicing of a ninth is 3 b7 9 13. THis contains all the color tines of the chord.

Reading Ukulele TAB - Alternate Notation

"TAB" or "Tablature", is an alternate form of musical notation, which tells players where to place their fingers on a particular instrument rather than which pitches to play. TAB is sort of a secret language between guitar players and ukulele players. Although a shortcut to getting started it actually serves to alienate one from the rest of the music world.

Standard Music Notation

Music notation or musical notation refers to various systems of writing music. Diverse systems of musical notation have developed in various cultures. In fact, many cultures simply do not notate their music in any form.

The Learning Process - The Mind, Hands and Ears

For music and learning an instrument like the ukulele or guitar, it's all about the making the connection between your Mind, your Hands, and your Ear. When listening to music, we enjoy it at the tempo the composer or artist intended, in real time. Only the ear is involved in listening. This is passive listening and you're simply enjoying the music. This is what we do every day and it's what draws us to want to learn a musical instrument.

Altered Seventh Chords on `Ukulele

Beyond basic open position chords, basic movable form chords, and a core set of 4-part chords. There are just too many chords shapes too memorize. Learning the principles of how chords are constructed and the ukulele fingerboard are the way to go. You can then create more advanced chords like 9#11, 7#5-9, 13b5, 7+9 on the fly as needed from your core set of chords.
