Melodic Intonation Therapy

MIT is based on neuroplasticity — the brain's ability to reorganise itself after damage. Many people with severe speech difficulties can still sing fluently, because singing draws on the right hemisphere of the brain, which is usually less affected by the left-hemisphere damage (often from stroke) that causes non-fluent aphasia.

By engaging melody and rhythm, MIT helps activate these alternative pathways, gradually strengthening the connections needed for speech production.

Good candidates usually have non-fluent (Broca's) aphasia, with speech that's slow, effortful, or limited, but with good understanding of spoken language. Being able to imitate simple words or phrases, and having the attention span for structured, repetitive practice, are both important.

Less suitable for global aphasia, significantly reduced comprehension, severe apraxia of speech, or significant cognitive impairments like dementia. People with fluent aphasia (like Wernicke's) may also benefit less, due to comprehension difficulties.

MIT is one of the more well-researched music-based aphasia therapies. Brain imaging studies have shown increased right-hemisphere activity after MIT, including in regions that mirror Broca's area on the left. Some studies have also found structural changes, such as increased white matter connectivity, associated with improved speech output.

Several reviews and meta-analyses support its effectiveness for improving functional communication, naming, and repetition in post-stroke non-fluent aphasia.

• 1. Select a phrase — short, functional, and meaningful to daily life
• 2. Find a baseline pitch — a simple 2–3 tone melody in the person's natural range
• 3. Hum and sing in unison — hum the tune, then sing the phrase together with hand tapping
• 4. Transition to natural speech — fade the melody and support while keeping the rhythm and stress
• 5. Independent speech — the phrase is used spontaneously, in real conversation

The Practice tab uses a six-step cueing hierarchy that breaks step 3–5 down further — from singing together, right through to spontaneous, everyday use.

• Hand tapping — tap the rhythm on a table or the person's hand as a kinesthetic cue
• Slow, deliberate pace — allow time for motor planning
• Repeat often — repetition strengthens the neural pathways being rebuilt
• Progress gradually — move from shorter to longer, simpler to more complex phrases
• Use meaningful phrases — a person's own name, common requests, or daily routines ("Time for lunch," "Where's my phone?") engage emotional and cognitive networks more strongly, which helps the brain build stronger, more durable pathways
