What is Acapella? Definition, History & How to Create Your Own (2026)

You've heard the term thrown around in music discussions, singing competitions, and movie soundtracks. But what exactly does "acapella" mean, and why has this centuries-old art form experienced a modern renaissance?

TL;DR: Acapella (or "a cappella") means singing without instrumental accompaniment — vocals only. The term comes from Italian, meaning "in the manner of the chapel." Today, you can create acapellas from any song using AI vocal isolation.

What Does Acapella Mean?

Acapella (noun): Music performed by voice alone, without instrumental accompaniment.

The term originates from Italian "a cappella," which literally translates to "in the manner of the chapel" or "in the style of the church." This refers to the traditional practice of church choirs singing without instrumental backing, particularly in Catholic churches where instruments were sometimes forbidden.

The Two Spellings

You'll see both spellings used:

Both are correct. "A cappella" (two words, double 'p', double 'l') is the traditional Italian spelling. "Acapella" (one word) is the common English adaptation. For modern music contexts, either works — just be consistent.

A Brief History of Acapella Music

Religious Origins (Medieval Era)

Acapella singing began in religious settings. Medieval churches used unaccompanied vocal music for worship:

• Gregorian chant — Single-melody vocal music in Catholic liturgy
• Byzantine chant — Eastern Orthodox tradition
• Synagogue music — Jewish vocal traditions

The church setting gave us the term "a cappella" — music sung "in the manner of the chapel."

Renaissance and Sacred Music (1400-1600)

The Renaissance era saw acapella reach artistic heights:

• Palestrina — Master of sacred polyphony (multiple voice parts)
• Josquin des Prez — Complex vocal compositions
• William Byrd — English choral traditions

This period established acapella as a serious art form with intricate harmonies and counterpoint.

Barbershop Quartets (1890s-Present)

American barbershop quartets brought acapella to popular entertainment:

• Four-part close harmony
• Distinctive "ringing" chord sound
• Originated in African American communities
• Spread through barbershop gathering culture

Barbershop remains popular today with organizations like the Barbershop Harmony Society preserving the tradition.

Doo-Wop Era (1940s-1960s)

Doo-wop brought acapella elements to popular music:

• Street corner singing groups
• Vocal bass lines ("doo-wop, doo-wop")
• Call-and-response patterns
• Influenced by gospel and R&B

Classic doo-wop groups created some of the earliest "pop" acapella recordings.

College A Cappella (1980s-Present)

American universities spawned a vibrant acapella scene:

• Yale Whiffenpoofs (founded 1909) — One of the oldest
• Competitive collegiate circuits
• Innovative arrangements of pop songs
• Inspired shows like Glee and movies like Pitch Perfect

Today, acapella enjoys mainstream popularity:

• Pentatonix — Grammy-winning acapella group
• Straight No Chaser — Viral YouTube to record deal

Creating Acapella Arrangements

Interested in arranging songs for acapella performance? Here's the basic process:

1. Choose Your Song

Best songs for acapella arrangements:

• Strong, recognizable melody
• Clear chord structure
• Moderate tempo
• Room for creative interpretation

2. Assign Voice Parts

Typical arrangement:

• Soprano — High female voice (melody or high harmonies)
• Alto — Lower female voice (mid harmonies)
• Tenor — High male voice (melody or harmonies)
• Baritone — Mid male voice (harmonies, rhythm)
• Bass — Low male voice (bass line)
• Vocal percussion — Beatboxer (rhythm)

3. Arrange the Parts

Key considerations:

• Inner voices fill out chords
• Vocal percussion replaces drums
• Syllables for non-melody parts ("doo," "ah," "dm," etc.)

4. Rehearse and Refine

Acapella requires:
