Musical Instruments — Play the Piano, Learn the Violin — English Grammar Exercises
She's a student at art school. The rich. The French. The 1950s. Seven special rules, one focused practice set.
Musical Instruments and the Definite Article
English uses the definite article the with musical instruments when referring to playing them as an activity. This is a fixed grammatical convention that applies universally: play the guitar, play the piano, learn the violin, practise the drums. The convention is believed to derive historically from a time when musical instruments were rare, expensive, and socially marked — the article signalled that one was playing the instrument (i.e., the one type), not a specific object. Today the rule is simply a lexical convention. A persistent learning difficulty arises because the parallel construction for sports uses zero article: play tennis, play chess. Learner corpora show that instrument–sport confusion generates a significant proportion of article errors at B1–B2 level.
Instruments: Always 'The'
My daughter is learning to play the violin.
He started playing the drums when he was ten.
She plays the guitar in a band.
Sports and Games: Zero Article
The direct contrast is worth memorising as a pair:
play chess (game — no article) ↔ play the piano (instrument — 'the')
play football (sport — no article) ↔ play the drums (instrument — 'the')
Mixed Sentences
When a sentence contains both a sport and an instrument, the two rules apply simultaneously:
Common Mistakes
✗ He started playing drums when he was ten. → ✓ playing the drums.
✗ My daughter is learning to play a violin. → ✓ play the violin.
Frequently Asked Questions
Why do we say 'the rich' and 'the French' without a noun?
'The + adjective' is a grammatical structure that refers to the entire group of people described by that adjective. 'The rich' = rich people in general; 'the French' = French people. The verb that follows is always plural: 'The rich are getting richer', not 'The rich is getting richer'. This pattern works with qualities (the young, the elderly, the poor, the homeless), states (the injured, the unemployed, the disabled), and nationality adjectives (the British, the Spanish, the Japanese).
Why do we use 'the' with musical instruments — 'play the piano' — but not with sports?
English uses 'the' with musical instruments when referring to playing them as an activity: play the guitar, play the violin, learn the flute. The convention treats the instrument as a generic representative of its type rather than a specific object. Sports and games use zero article: play tennis, play chess, go swimming. The two rules are parallel opposites and must be memorised separately.
What is the difference between 'go to school' and 'go to the school'?
Institutional nouns — school, hospital, prison, church, university, bed — drop the article when used for their primary purpose. 'Go to school' means attending as a student; 'go to the school' means visiting the physical building for any other reason (as a parent, a plumber, a visitor). The same distinction applies throughout: 'in hospital' (as a patient) vs 'at the hospital' (visiting someone), 'in prison' (as a prisoner) vs 'visiting the prison'.
Why do decades and ordinal numbers always use 'the'?
Both decades and ordinals identify a unique or specific position, which triggers the definite article. 'The 1960s' refers to one specific ten-year period within history — it is not one of many possible 1960s. Similarly, 'the first', 'the second', and 'the last' point to a unique position in a sequence. You cannot say 'a first time I did this' when referring to the specific incident — it must be 'the first time'.
