What is the major tenth interval?
The major tenth is the compound form of the major third, extending that interval's bright, happy quality across a wider register. Like its minor counterpart, the major tenth benefits from the added octave of spacing that prevents muddiness in lower registers. This makes it essential for creating full-sounding major harmonies in piano, guitar, and orchestral arrangements.
Beethoven famously required large hand spans in his piano sonatas, frequently writing passages in tenths that demand both technical facility and musical sensitivity. Chopin, Liszt, and Rachmaninoff continued this tradition, using major tenths as a foundation for rich left-hand accompaniment patterns. The interval's combination of harmonic clarity and emotional brightness makes it one of the most satisfying sounds in tonal music.
Harmonic character
The major tenth is consonant and stable, sharing the major third's quality of brightness and resolution while sounding more spacious and resonant. In the lower register, where close-position major thirds can sound thick and cluttered, the major tenth provides the same harmonic information with pristine clarity. This acoustic advantage explains why skilled arrangers consistently prefer open voicings with tenths over close-position thirds.
- Compound equivalent: major third + octave

- Common context: Open voicings, stride piano, fingerpicking
- Genre associations: Classical, jazz, folk, pop
Where you'll hear it
Major tenths feature prominently in classical piano literature. Beethoven's "Waldstein" Sonata opens with repeated major tenth patterns that create a luminous, powerful texture. Chopin's etudes and ballades frequently employ tenths in the left hand, demanding both stretch and control. In the Romantic era, the ability to play tenths fluently was considered essential for any serious pianist.
On guitar, major tenths appear naturally in fingerpicking patterns where the thumb plays bass notes on the lower strings while fingers pluck the third on upper strings. Country, folk, and classical guitar styles all use this voicing extensively. In jazz, major tenths form the backbone of rootless voicings and walking bass lines, where the wide spacing creates a professional, polished sound that close voicings cannot match.
Practice ideas
Start by playing major thirds and then dropping the lower note by an octave to create major tenths. Practice major and minor tenth pairs in all keys to internalize the difference. On piano, if your hand cannot span a tenth, practice rolling or arpegiating the interval—many professional pianists with smaller hands use this technique effectively. Guitar players should practice tenth shapes across different string groups, combining bass notes with thirds on higher strings to create full, open harmonies.
