My musical mind just pulled this Major 6th interval reference melody out of the music-sphere.
I believe I’ve heard it as an intro and a transition. Can’t think of any specific song, but the melody stands out. For the video tune, click on “Ear Training Sixth Interval Reference Melody” in the link below.

Have a look this lesson.

There it is.

Sorry, I’m a little confused.
The major third interval should be 3 tones, not 2 tones, right?
And how many tones/semitones is the major sixth interval from the root note? Thank you.

A major 3rd is 4 semitones; a major 6th is 9 semitones.

A major 3rd is the 3rd note of the major scale, the 6th interval the 6th note of the major scale.

The answers you have above are correct, but I thought I’d add a bit more colour in case it helps …

A semitone is a distance or inteval of 1 fret on the guitar. A tone is two semitones or 2 frets.
The notes in the major scale major scale always follows this formula …

A tone between notes 1 and 2
A tone between notes 2 and 3
A semitone between notes 3 and 4
A tone between notes 4 and 5
A tone between notes 5 and 6
A tone between notes 6 and 7
A semitone between notes 7 and 8 (the octave)

Often this is just written as “T T S T T T S” for short.

In the C major scale the notes are C, D, E, F, G, A, B, C so there is a tone between all notes except between E and F and between B and C where there is a semitone.

A major 3rd is the distance between notes 1 and 3, so the distance between C and E. So that’s 2 tones, or 4 semitones or 4 frets.

A major 6th is the distance between notes 1 and 6, so the distance between C and A. So that’s a total of 4 tones and one semitone. So that’s 9 semitones or 9 frets.
