🔍 Objective:

Identify the size of each musical interval (e.g., 2nd, 3rd, 4th, etc.) between the two notes in each measure. We are to write the interval size below each pair.

We’ll go through each row one at a time.

🦖 Row 1 – Treble Clef (Brown Dinosaur)

Notes:
1. C to E → C to E is a major 3rd → 3rd
2. G to B → G to B is a major 3rd → 3rd
3. A to F → A to F is downward, but we count upward from the lower note. From A up to F is a 6th (A–B–C–D–E–F), so it's a 6th.
- But wait — this is actually A to F above, which is A-B-C-D-E-F = 6 notes → 6th
- However, since F is lower than A, and we're looking at the interval as written, we need to check direction.
- The interval is from A down to F, but intervals are typically measured upward unless otherwise specified.
- So we should count from the bottom note up.
- Here, F is lower than A, so the interval is F to A? No — the notation shows A above F?

Wait — let’s look carefully:

Actually, in standard notation, the bottom note is the starting point, and the top note is the ending point.

But here, the first pair is:
- First note: C (middle C)
- Second note: E above C

So:
1. C to E: 1st (C), 2nd (D), 3rd (E) → 3rd
2. G to B: G, A, B → 3rd
3. A to F: A is higher than F, but the second note is F below A?
- Wait — the third pair is: A (on space) to F (below on line) → So A to F is downward.
- But interval size is determined by counting upward from the lower note.
- So we consider F to A: F-G-A → 3rd
- But the notes are written as A above F, so the interval is from A down to F → that would be a 6th downward, but we name intervals by the distance upward.
- So: F to A is a 3rd, but since A is the upper note and F is lower, the interval is F to A = 3rd, but the notation shows A to F, meaning from A to F — which is downward, so we still measure from the lower note up.

Wait — better approach:

> In music, an interval is named based on the number of scale degrees between the two notes, counting from the lower note to the upper note.

So we must identify:
- Which note is lower
- Count how many steps up to the higher note

Let’s go one by one.

#### ✔ Row 1: Treble Clef (Brown Dino)

1. C to E: C (1), D (2), E (3) → 3rd
2. G to B: G (1), A (2), B (3) → 3rd
3. A to F: A is higher than F? Let's see:
- A is on the space between lines 4 & 5
- F is on the line below middle C → F is lower than A
- So lower note is F, upper note is A
- F to A: F-G-A → 3rd
- So F to A = 3rd
- But the notation shows A then F — but the interval is still F to A, so 3rd
- So answer is 3rd
4. D to F#: D to E to F# → D (1), E (2), F# (3) → 3rd
5. D to F: D to E to F → 3rd

Wait — fourth pair: D to F#
- D to E (2nd), E to F# (3rd) → 3rd
- Yes, minor 3rd or major 3rd? But we’re just asked for the size, not quality.

So we only need the number of the interval.

So:
1. C–E → 3rd
2. G–B → 3rd
3. A–F → F to A → 3rd
4. D–F# → 3rd
5. D–F → 3rd

Wait — last one: D to F → D–E–F → 3rd

All seem like 3rds?

Wait — let’s double-check the third pair: A to F — if A is higher, and F is lower, then the interval is from F to A, which is 3rd, yes.

But what about the spacing?

Wait — let’s look at the actual staff positions.

In treble clef:

- C is on the line below the staff (middle C)
- E is on the second line up → so C to E: 3rd
- G is on the top line, B is on the space above → G to B: 3rd
- A is on the space above G, F is on the line below C → so A is high, F is low → F to A is 3rd → correct
- Next: D to F# → D is on the first line, F# is on the third line → D–E–F# → 3rd
- Then D to F → D–E–F → 3rd

So all five are 3rds?

Wait — no! Look at the fourth pair: D to F# — but F# is two half steps above D → that's a minor 3rd? But again, we only care about size.

Wait — interval size is counted by scale degree, not quality.

So:
- C to E: 3rd
- G to B: 3rd
- A to F: F to A = 3rd
- D to F#: 3rd
- D to F: 3rd

So all five are 3rds?

But let’s recheck the third pair: A to F — is F really below A?

Yes: A is on the space above the top line (above G), F is on the line below middle C → so yes, F is lower than A → interval is F to A = 3rd

So answers:
3rd, 3rd, 3rd, 3rd, 3rd

Wait — that seems suspiciously uniform.

Wait — look at the fourth pair: D to F# — D is on the first line (D), F# is on the third line → that’s D–E–F# → 3 notes → 3rd

But what about the fifth pair: D to F — D to E to F → also 3rd

Wait — maybe I’m missing something.

Wait — let’s look at the actual image description.

Wait — perhaps I misread the notes.

Let me reconstruct the staffs.

📐 Staff Analysis

Let’s do this carefully.

🦖 Row 1: Treble Clef (Brown Dino)

1. First measure: C (middle C) to E (E above C) → C to E → 3rd
2. Second measure: G (top line) to B (space above) → G to B → 3rd
3. Third measure: A (space above G) to F (F below middle C) → A is higher than F → so lower note is F, upper is A → F to A → F-G-A → 3rd
4. Fourth measure: D (first line) to F# (third line) → D to E to F# → 3rd
5. Fifth measure: D (first line) to F (second line) → D to E to F → 3rd

✔ All 3rds

But wait — the example says "Ex. 5th", so they expect numbers like 2nd, 3rd, 4th, etc.

So far: 3rd, 3rd, 3rd, 3rd, 3rd

Hmm.

Wait — fourth measure: D to F# — is that really a 3rd?

D to E = 2nd, E to F# = 3rd → yes, 3rd

But F# is one half-step above F, so D to F# is 3 semitones, which is a minor 3rd, but size is still 3rd

So yes.

Now let’s move on.

🦕 Row 2: Bass Clef (Blue Dino)

Bass clef: notes are lower.

1. First measure: D (in bass clef) to C → D is higher than C? Let's see:

In bass clef:
- Middle C is on the line above the staff
- D is on the space above that → so D is higher than C

So lower note is C, upper is D → C to D → 2nd

2. Second measure: E to C → E is higher than C? E is on the line below middle C, C is on the line above? Wait:

Wait — bass clef:

- Lines: G, B, D, F, A (from bottom to top)
- Spaces: A, C, E, G

Standard:

- Bottom line: G
- Then: B, D, F, A
- Top line: A

Spaces: A, C, E, G

Middle C is on the line above the staff (the ledger line).

So:
- C is on ledger line above staff
- E is on second line from bottom → so E is lower than C

So E to C: E is lower, C is higher → E to C → E-F-G-A-B-C → that’s 7 notes → 7th

Wait — E to C: E (1), F (2), G (3), A (4), B (5), C (6) → 6th

Wait — E to C: E–F–G–A–B–C → six scale degrees → 6th

But C is higher than E, so E to C = 6th

But the notation shows E then C, so interval is E to C → 6th

3. Third measure: C to B → C is on ledger line above, B is on top line of bass clef → B is higher than C?

No — B is on top line of bass clef → that’s B below middle C

Middle C is above the staff.

So:
- C is on ledger line above staff
- B is on top line → B is lower than C

So lower note is B, upper is C → B to C → 2nd

4. Fourth measure: G to F# → G is on second line from bottom, F# is on third line from bottom → F# is higher than G?

No — G is on second line, F is on third line → F is lower than G

So G is higher than F# → lower note is F#, upper is G → F# to G → 2nd

5. Fifth measure: C to D → C is on ledger line above, D is on space above → D is higher than C → C to D → 2nd

Wait — let’s list them:

1. D to C → D is higher than C → lower note is C, upper is D → C to D → 2nd
2. E to C → E is lower than C → E to C → E-F-G-A-B-C → 6 notes → 6th
3. C to B → C is higher than B → B to C → 2nd
4. G to F# → G is higher than F# → F# to G → 2nd
5. C to D → C to D → 2nd

So answers:
- 2nd, 6th, 2nd, 2nd, 2nd

Wait — that seems odd.

Let’s double-check:

1. D to C: D is on space above middle C (bass clef), C is on ledger line above → wait, no!

Wait — in bass clef:
- Middle C is on the ledger line above the staff
- D is on the space above that → so D is higher than C
- So D to C → D is higher, C is lower → interval is C to D → 2nd

Yes.

2. E to C: E is on second line from bottom → E below middle C
C is on ledger line above → C above middle C
So E is lower, C is higher → E to C → E-F-G-A-B-C → 6 notes → 6th

3. C to B: C is on ledger line above, B is on top line → B is lower than C → so B to C → 2nd

4. G to F#: G is on second line from bottom, F# is on third line from bottom → F# is higher than G? No — G is on second line, F is on third line → F is lower than G, so F# is lower than G → so G is higher, F# is lower → F# to G → 2nd

5. C to D: C on ledger line, D on space above → D is higher → C to D → 2nd

So: 2nd, 6th, 2nd, 2nd, 2nd

Okay.

🦖 Row 3: Treble Clef (Green Dino)

1. B to D: B is on space above G, D is on first line → D is lower than B? No — D is on first line, B is on space above G → B is higher than D

So lower note is D, upper is B → D to E to F to G to A to B → 6 notes → 6th

Wait — D to B: D–E–F–G–A–B → 6 steps → 6th

2. D to F#: D on first line, F# on third line → D–E–F# → 3rd

3. G to G: same note → unison → 1st

4. C to E: C to E → 3rd

5. F to A: F on second line, A on space above → F to G to A → 3rd

So:
- 6th, 3rd, 1st, 3rd, 3rd

---

🦕 Row 4: Bass Clef (Yellow Dino)

1. F to D: F on third line, D on space above → D is higher than F → F to D → F-G-A-B-C-D → 6 notes → 6th

2. C to E: C on ledger line above, E on second line from bottom → E is lower than C → so E to C → E-F-G-A-B-C → 6th

3. E to G: E on second line, G on second line from bottom → G is lower than E → G to E → G-A-B-C-D-E → 6th

Wait — E to G: E is higher, G is lower → so lower note is G, upper is E → G to E → G-A-B-C-D-E → 6 notes → 6th

4. D to F: D on space above, F on third line → F is lower than D → F to D → F-G-A-B-C-D → 6th

5. E to G: same as above → 6th

Wait — let’s confirm:

1. F to D: F on third line, D on space above → D is higher → F to D → F-G-A-B-C-D → 6th
2. C to E: C on ledger line above, E on second line from bottom → E is lower → E to C → E-F-G-A-B-C → 6th
3. E to G: E on second line, G on second line from bottom → G is lower → G to E → G-A-B-C-D-E → 6th
4. D to F: D on space above, F on third line → F is lower → F to D → F-G-A-B-C-D → 6th
5. E to G: same as #3 → 6th

So all 6ths

✔ Explanation Summary:

- Interval size is determined by counting scale degrees from the lower note to the upper note.
- Always identify the lower note and upper note, then count upward.
- Ignore direction; always measure upward.
- Example: A to F → F is lower, A is higher → F to A = 3rd
- Unison (same note) = 1st
- Octave = 8th

This worksheet helps students practice identifying intervals by visual spacing on the staff.
