Benefits gained from practice
The benefits of practicing the diatonic triad include
- Understanding chord tones to learn the basics of playing bass lines and solos.
- Understanding the position and fretboard
- Learning correct fingering
- Finger strengthening
- Establishment of volume and tone
- Improvement of pitch and tone
Points to keep in mind when practicing
Please practice the following items to increase the effectiveness of your practice.
- Check what chord you are playing as you play it. (This is the most important)
- Play while checking what note you are playing. (Think of notes alphabetically, like C or B flat.)
- Play with an understanding of which position you are holding.
- Do not use a faster tempo setting. The score is set to bpm=60, but it can be slower.
- Practice until you can play without making a single mistake.
Fingering Concept
If you have been reading this jazz bass course, you already understand fingerings, but let's review them again here.
Important elements of fingering include
- Play in a position that covers as many notes as possible.
- Select a position that can cover many notes when moving from one position to another.
- Reduce the number of times you move positions.
- Avoid pinky to pinky shifting whenever possible. (except for glissandos, etc.)
- The G, D, and A notes should be played on the open strings from the standpoint of tone and ease of position movement. (Depending on the phrase, it may be better to hold them.)
To summarize the aboveChoosing fingerings that are rational, lean, and minimize positional shifts as much as possible is a major key to progress.
diatonic triad
As a basic exercise to play triads freely, diatonic triads will be the subject of this Part 20.
A diatonic triad is a diatonic chord without the seventh degree note, meaning three chords in the first, third, and fifth degrees.
Diatonic chords are also explained below.

The following will be a diatonic triad in the C major scale. (Chord names are given at the top and degree names at the bottom)

If it is a major scale diatonic triad, the degree name such as "I" or "IIm" will not change, just like a 4-chord diatonic chord.Diatonic triads should also be remembered by their degree names.This has the advantage of being able to respond immediately if the Key changes.
For example, if Key=F, the chord type and degree name remain the same.

Diatonic Triad Practice
Here are two basic exercises for the diatonic triad. Please work on them while keeping the aforementioned points in mind.
- Pattern 1: Practice playing 1, 3, and 5 degrees for the ascending form and 5, 3, and 1 degrees for the descending form
- Pattern 2: Practice playing 1, 3, 5 degrees and 5, 3, 1 degrees alternately.
Below are the scores for Patterns 1 and 2 in Key=C, though,The music score written in 12Key for Pattern 2 is available for download at the bottom of this page.
The numbers above the notes are fingering, and the positions are listed below。
