Interleaved practice is a way of organizing a practice session so that you rotate between different pieces, skills or passages, instead of repeating one thing until it feels solid. It is often recommended as a way to make learning last, though it can feel less comfortable at first. This article explains the idea, what is known about it, and how to apply it at the piano.
What interleaved practice means
In interleaved practice you mix different items within a single session. For example, you might spend a few minutes on a scale, then a few minutes on a difficult passage, then a different piece, then return to the scale. The key feature is switching before any one item feels finished.
The idea comes from research in learning and motor skills, and it is now commonly discussed by music teachers. You may also see it described alongside related ideas such as varied practice and distributed (spaced) practice.
Blocked vs interleaved practice
Blocked practice means working on one item for a long, continuous stretch: the same scale, the same piece, or the same four bars, repeated many times.
Interleaved practice means alternating between items in shorter chunks and coming back to them later.
Blocked practice often feels better in the moment, because your playing improves quickly during the block. Some educators describe this as an “illusion of fluency”: the passage sounds good right now, but that does not guarantee you can play it tomorrow or in a different context. Interleaving forces you to reload the passage each time you return to it, which is closer to what happens in performance.
Why it may help
The usual explanation is that switching tasks makes your brain retrieve and reconstruct the skill each time, rather than relying on short-term repetition. Studies in other motor and learning tasks have often found that interleaved schedules lead to better retention and transfer, even when performance looks worse during practice.
It is worth being honest about the limits. Research specifically on music practice is smaller than research on general learning, and results vary by age, skill level and task. Interleaving is a promising tool, not a guaranteed shortcut. Try it for a few weeks and see how it works for you.
How to do it at the piano
There are several easy ways to interleave:
- Rotate pieces. Instead of playing one piece ten times, alternate between two or three pieces.
- Rotate sections. Move among different trouble spots within one piece, such as the bridge, the ending and the left-hand passage in the middle.
- Rotate skills. Alternate between a scale (see practicing piano scales), a sight-reading example and a repertoire passage.
- Change the order each day. Starting with a different item gives you a fresh test of what you remember.
- Use a timer or a card system. Write tasks on cards, shuffle them, and work through them for a few minutes each.
A sample 30-minute interleaved session
- 3 minutes: warm-up scale
- 5 minutes: hardest passage from Piece A
- 5 minutes: hardest passage from Piece B
- 3 minutes: sight reading
- 5 minutes: second pass at Piece A passage
- 5 minutes: second pass at Piece B passage
- 4 minutes: play the full scale again or run through a piece you know
Notice that each passage appears more than once. This is intentional. The returns are where the learning happens.
Choosing what to mix
You do not need to interleave everything. Some guidelines:
- Mix items that are related but different, such as two passages from the same piece or two pieces at a similar level.
- Avoid switching so quickly that you can never settle in. Three to five minutes per item is a reasonable starting point for most people.
- Keep each chunk small and specific: “left-hand jump in bar 12” is better than “piece”.

When blocked practice is still useful
Blocked practice has a place. When you first meet a new passage, you often need some focused repetition to get the notes and fingering right. A short block at the start, followed by interleaving once the passage is roughly working, is a common compromise. You may also use blocked practice for slow, careful work on technique where you are fixing a specific movement.
Why it feels harder
Interleaving often makes practice feel messier. You may make more mistakes during the session, and progress can seem slower. Many educators note that this “desirable difficulty” is part of why it works, but it can be discouraging. Give it a few sessions before you judge it, and compare how well you remember passages the following day.
If you are also working toward performing from memory, interleaving pairs well with the methods in how to memorize music, since both rely on retrieving material rather than just repeating it.
FAQ
What does interleaved practice mean?
It means alternating between different tasks or passages within a practice session, rather than finishing one before starting the next.
Is it “music practice” or “music practise”?
In American English, “practice” is used for both the noun and the verb. In British English, “practice” is the noun and “practise” is the verb. Either is fine as long as you are consistent.
What is integration in music?
The word is used in several ways, and the question does not point to one standard meaning. In practice discussions, it most often refers to combining separately practiced parts, such as hands together or sections into a whole piece. If you meant something else, check the context where you saw it.
Is there a “35 year rule” in music?
There is no widely recognized rule by that name in piano practice that we can confirm, so we would treat the phrase with caution unless you can find its source.
