You can use HowTo schema.
“How-to” snippets aim to provide step-by-step instructions directly in the SERPs for instruction-based queries.
But before adding this schema, you need to add these instructions on your page.
Example -
Step 1 - C Major Chord (Open Position)
Step 2 - C Major Chord (based on A major shape)
Step 3 - C Major Chord (based on G major shape)
Step 4 - C Major Chord (based on E major shape)
Step 5 - C Major Chord (based on D major shape)

After adding these steps, schema for these steps will be like -
<script type="application/ld+json">
{
"@context": "http://schema.org",
"@type": "HowTo",
"name": "Learn the C maj guitar chord",
"step":[
{
"@type": "HowToStep",
"text": "C Major Chord (Open Position)",
"image": "https://example.com/1x1/photo.jpg"
}, {
"@type": "HowToStep",
"text": "C Major Chord (based on A major shape)",
"image": "https://example.com/1x1/photo.jpg"
}, {
"@type": "HowToStep",
"text": "C Major Chord (based on G major shape)",
"image": "https://example.com/1x1/photo.jpg"
}, {
"@type": "HowToStep",
"text": "C Major Chord (based on E major shape)",
"image": "https://example.com/1x1/photo.jpg"
}, {
"@type": "HowToStep",
"text": "C Major Chord (based on D major shape)",
"image": "https://example.com/1x1/photo.jpg"
}
]
}
</script>
Modify the schema according to your steps.
