What are the notes on C harmonica?
As a new harmonica player, you might be confused about the notes. Some notes may seem “missing.” This article will cover the notes on a C harmonica and the reasoning behind their layout.
Harmonicas come in various keys, but the most common key is C.
C harmonica notes are based on the “Richter tuning” system, which is used for most harmonicas. The blow and draw notes for a harmonica in the key of C are shown in the diagram below:
If you look at holes 4 to 7, you’ll notice that the notes from these holes form a C major scale:
C, D, E, F, G, A, B, C.
However, holes 1 to 4 differ, and the lower notes do not form a major scale. But, if you look at the blow notes from holes 1 to 4 (C, E, G, C), they form a C major chord. So, when you blow into these first 4 holes, you’ll hear how these notes seem to “agree” with each other when played together.
The blow notes from holes 4 to 7 (C, E, G, C) also form a C chord, and the blow notes from holes 7 to 10 (C, E, G, C) form yet another C chord. This is no coincidence, and that’s why all the blow notes come from the C Major chord on the harmonica.
The draw notes from holes 1 to 4 (D, G, B, D) come from the G chord. This chord is essential in the key of C. When you blow and draw on holes 1 to 4, you will hear how the two chords match.
The Richter tuning system used on most harmonicas provides chords in the bottom four holes. It also allows a major scale in the middle holes. This is the main reason for its design.
Is 1 on a harmonica the highest note or the lowest?
The first blow note on the first hole is the lowest harmonica note and should be on your left side.
The Missing Notes on Harmonica
As you can see from the notes on the lower and upper octaves, we have some missing notes. On the lower octave, the missing notes are F and A.
And the missing note on the upper octave is B.
The Richter tuning system is used on most harmonicas. It is based on having chords in the lowest four holes. The middle holes have a major scale. Some notes are not available, especially at the bottom. However, “bending” is a technique that helps the player reach these missing notes.

Bending harmonica notes involves adjusting your tongue position, mouth shape, and breath control. This can be hard for new harmonica players.
Bending a note lowers its pitch and is mainly done on draw holes 1, 2, 3, 4, and 6 and blow holes 8, 9, and 10. The note layout below shows the standard bend notes on a C harmonica:
Blues Harmonica Bending Basics
The technique called bending lets harmonica players make cool sounds by changing how they breathe and move their mouth. When you use the proper breath pressure, tongue position, and mouth shape, you can make notes sound different.
Bending a note lowers its pitch, which means it makes the sound go lower, like when your voice gets deeper. This breath technique is what makes the blues harmonica sound so sad and soulful, and it’s done by controlling how air flows through the harmonica while you play.
How to Memorize Notes on Blues Harp?
When learning the notes on the harmonica, it’s fine to memorize some of them. This is especially true for the keys you use less often. Here is a simple way to memorize the notes.
As shown below, memorize the blow notes as shown in the blocks:
[C E G] [C E G] [C E G] C
For the draw notes, memorize the notes as shown in the blocks:
[D G] [B D F A] [B D F A]
What is a C harmonica used for?
A C harmonica is one of the most popular harmonicas for beginners and pros alike. Here are its primary uses:
First position (Straight Harp): Playing melodies in the key of C major. This is great for folk music, pop, and other major key songs.
Second position (Cross Harp): Playing blues, rock, and country in the key of G. This is where bending notes are handy, allowing for expressive, bluesy sounds. The cross-harp is the most common position for playing blues on a C harmonica.
Third position: This position works well for playing in D minor or D Dorian mode. It is popular for minor blues, jazz songs, and Irish music.
The C harmonica is versatile. It is often chosen as the starting key. This is because it works well with many beginner lessons and exercises.
What chords are on a harmonica in the key of C?
There are two primary chords naturally built into a diatonic harmonica, especially when played in the first position:
C major chord (blow notes): When you blow on holes 1 to 10, you are playing notes that form a C major chord (C, E, G). You generally work on the first four holes for a fatty chord sound.
G major chord (draw notes): When you blow air through holes 1, 2, 3, and 4, you play a G major chord. This chord includes the notes G, B, and D. It is the main chord in the C scale.
If you play draw notes on holes from 2 to 5, you’ll have a G7 (G, B, D, F), the dominant seventh chord of the C scale.
Also, you can play the Dm chord by drawing holes 4 to 6 (D, F, A).
This chord becomes important in cross-harp playing (second position) for blues in the key of G.
Final Thoughts
The Richter tuning system is used on most harmonicas. It provides chords in the lower four holes and a major scale in the center holes. To do this, some notes are not included, especially in the lowest holes. However, this deficiency can be countered using a technique called “bending,” which allows these absent notes to be played.
In conclusion, learning the notes on a harmonica can be confusing at first. However, with practice, you can master them. Remember, it’s not necessary to remember all the notes, and you can focus on scale degrees instead. With dedication and patience, you can progress in your harmonica playing skills.
