How to use an Accordion bass chart

To get optimal sound out of your accordion, you have to know how to use its bass buttons at the right time and with the right emphasis. It all begins with understanding the different types of bass buttons and how to read an accordion bass chart properly.

Types of Bass button

There are different types of accordion bass, they can be either 120 bass buttons, 96, 72, 48, 40, 12, or 8. The bass button is on the bass side. The bass buttons arranged on the accordion are in rows and columns containing different notes. The note names are the basic bass, counterbass, and chords. All the notes on this instrument help the accordionist produce different sounds.

Let us look at the types of bass buttons and the note available on them.

The 120 bass button stradella chart

This piano accordion bass is the standard bass note for most accordions. The note of this one is very common among accordionists. Many accordionists prefer to use this stradella bass because it has enough notes that will be needed to compose a sound. This button stradella bass has no hidden categories, as all the notes are shown.

How to play the 120 bass button stradella bass

If you are a beginner and you want to get to know how to play the 120-buttoned one, you need to know how to read the sheet music, a mental structure of the bass layout, how to place your fingers, and how to move your fingers around the buttons.

Starting with the piano fingering, (if you are making use of the right-hand accordion); your right arm should be on the piano key. You can start by placing your second finger (index finger) on the keyboard, then your middle finger, ring finger, and little finger will follow. The thumb is not used when playing the right side.

Fingering the bass notes can be done easily by finding the major bass note like the C major. Finding the C bass is not so difficult because it has a particular shape. You can also use the E bass or the A flat in place of the C major. The two keys are also shaped in a certain way for the accordionist to know when his or her finger touches them. The C major serves as a starting ground.

To start with, your fingering style should be in this order – the middle finger should be on the major chords, the basic basses can be controlled by the ring finger, and your index finger can play the minor chords, minor 7th chord, and the diminished chords. This allows for a perfect flow of the bass notes while playing the accordion. On the 120 accordion bass, the row closest to the bellow is the counterbass row, then the second row is fundamental bass notes, and the last four columns are the chords.

Getting a good mental map of how the bass layout is will help you as an accordionist play better. Always remember that the chord buttons are the last four columns, perhaps this can help.

Take the example of the diagram below

96 bass note piano accordion chart

The 96 buttons accordion bass has single bass notes in 2 columns. The rest of the buttons are chords (4 columns). This accordion bass does not have a different fingering style from the 120-button bass. The only difference is the size and weight of the accordion. The four columns still have the minor chords, minor 7th chord, major chords, and the diminished chords. This accordion and the 120 buttoned accordion bass are most commonly used by accordionists. They both can be used to make classical music. You may use the same fingers for pressing the bass note.

Take the example of the diagram below

72 bass accordions chart

This one has fewer buttons than the two mentioned above. The weight is lighter than theirs and the size is smaller. Most beginners prefer to use this kind of accordion because they offer fewer buttons to be covered by them. The layout of the buttons on this accordion is almost like the 96 and 120 accordion bass notes. The first two columns are known as the root note. The one close to the below is the counter bass row, and the second row is the basic bass note. It also has 4 columns for the chord notes, that is (the minor chord, major chord, minor 7th chord, and diminished.) All the chords are in twelve keys. The C bass here is just as important as it is in the other accordions.

Take the example of the diagram below

48 bass accordion

There are two types regarding the layout of this accordion. These are the 12 by 4 layout and the 8 by 6 layout. We will take them one after the other for better understanding and so we will not mix up the two accordions.

12 by 4 bass notes

The 12 by 4 is a good one for beginners because of the few buttons it has on it. It has two columns known as the root note. The root note consists of the basic bass and counter bass. The counter bass row is above the basic bass row. Unlike the other 3 accordions above, this one has some missing chords as the chord has just two columns. The accordionist cannot play the minor 7th chord and the diminished note. Since there is the presence of the basic bass row, the C bass or C major is still available on this accordion.

Take the example of the diagram below

8 by 4 bass notes

The 8 by 4 is a good one for beginners because of the few buttons it has on it. It has two columns known as the root note. The root note consists of the basic bass and counterbass. The counterbass row is above the basic bass column. In opposition to the 12 by 4 accordion, this one has a complete 4 column for the chords although it has some keys that are missing on the bass side. The missing keys are the F sharp/Gb, the B button, Ab/G sharp, and Db/C sharp.

Take the example of the diagram below

40 bass accordions

The 40 bass accordion has lesser buttons than the 48-buttoned one. It is also good for new learners because of the smaller amount of buttons on it. The button structure goes like this – there is still the presence of the counterbass row and basic bass, making it has two rows of root notes. It has three columns of chords with the absence of a diminished chord. The bass rows do not have a complete set of minor 7th buttons.

The unique thing about is one is even though it does not have the diminished chord, it can still be played by omitting the counter bass and basic bass button while fingering the minor 7th.
