How do you tell apart the repeating patterns in the National 5 list - ostinato, riff, pedal and drone - when you hear them in an excerpt?
Identifying repeated and sustained patterns in the National 5 concept list: ostinato, riff, pedal and drone, and how each underpins a piece of music.
How to tell apart the National 5 Music repeating patterns: an ostinato (a repeated melodic or rhythmic pattern), a riff (a repeated pattern in pop, rock and jazz), a pedal (a held or repeated note under changing harmony) and a drone (a continuous held note common in Scottish and folk music).

What this concept is asking
National 5 Music asks you to recognise repeated and sustained patterns that hold a piece together. The concept list includes ostinato, riff, pedal and drone. All four involve something being repeated or held, which is exactly why candidates confuse them, so the skill is hearing which kind of repetition you are listening to and naming the right concept word.
These patterns usually sit underneath the main melody as a foundation. Spotting them is often easier than spotting melodic detail, because they repeat, giving you several chances to hear them clearly.
The patterns in the National 5 list
Ostinato is a repeated melodic or rhythmic pattern that continues throughout a section or piece. The word is Italian for "obstinate", because it stubbornly keeps going. It is the general, often classical, term for a persistent repeated figure.
Riff is the pop, rock and jazz version of an ostinato: a short, catchy musical pattern repeated through a song, usually on guitar, keyboard or bass. A famous guitar hook that you recognise instantly is a riff.
Pedal is a single note, often in the bass, that is held or repeated while the harmony above it changes. Because the harmony moves but the pedal stays, it builds tension or a sense of anchoring. A pedal can be a tonic pedal (on the home note) or a dominant pedal (on the fifth).
Drone is a continuous sustained note, or pair of notes, held under a melody. It is the signature sound of the bagpipes and is central to Scottish and other folk and world music. Unlike a pedal, it usually does not change at all and is more about timbre and atmosphere than harmonic tension.
How to tell them apart by ear
Ask two questions. First, does the pattern have a clear melodic or rhythmic shape that repeats, or is it just one sustained note? A repeating shape is an ostinato (classical) or a riff (pop, rock, jazz); a single held note is a pedal or a drone. Second, if it is a held note, does the harmony above it change? If yes, it is a pedal; if the whole texture sits still on the note (especially under bagpipes or folk), it is a drone.
Examples in context
The driving two-bar guitar figure that opens a rock anthem and returns throughout is a riff. A repeated low cello pattern under a Baroque piece is an ostinato (and if it is in the bass and the structure is built on it, it may be a ground bass). A held organ note in the bass while chords shift above it is a pedal. The unchanging low note under a set of bagpipes is a drone.
Try this
Q1. A short, instantly recognisable bass guitar pattern repeats through a funk track. Name the concept. [1 mark]
- What the marker wants. Riff, because it is a short repeated catchy pattern in a pop, rock or jazz style.
Q2. An organ holds a low bass note while the chords above it change for several bars. Name the concept. [1 mark]
- What the marker wants. Pedal, a held or repeated note under changing harmony.
Q3. Why would you call the held note under a set of bagpipes a drone rather than a pedal? [1 mark]
- What the marker wants. Because a drone is a continuous, unchanging note typical of bagpipe and folk music, while a pedal implies harmony changing above the held note.

SQA N5 style1 marksA bagpipe tune is played over a single continuous note that never changes throughout the excerpt. Name this concept. (1 mark)Show worked answer →
The answer is drone. A drone is a continuous sustained note (or pair of notes) held under a melody, and it is a defining feature of bagpipe music and much Scottish and folk music.
The marker wants the concept word "drone". Do not write "pedal", because although a pedal is also a held note, the drone is the term examiners expect for the continuous Scottish or folk sustained note, especially under bagpipes. The clue is "continuous note that never changes" beneath a folk tune.
SQA N5 style2 marksListen to the rock excerpt. (a) Identify the short repeated pattern played by the guitar throughout. (b) State one reason this pattern helps the song. (2 marks)Show worked answer →
Part (a) is one mark. A short, catchy musical pattern repeated throughout a pop, rock or jazz number is a riff. (If the question were about classical music, the same idea repeated would be called an ostinato.)
Part (b) is one mark for a sensible musical reason, for example that the riff gives the song a recognisable hook, drives the rhythm, or unifies the track by recurring. Name the concept correctly, then give one clear reason. Two parts, two marks.
