Task: Identify the Melodic Intervals

We are given a series of two-note melodic intervals in the Key of C, and we must identify each interval as:
- Unison
- 2nd
- 3rd
- 4th
- 5th
- 6th
- 7th
- Octave

We will go through each pair of notes in order, determine the interval between them, and label it accordingly.

Understanding Melodic Intervals

A melodic interval is the distance between two pitches played one after the other (not simultaneously). We count the number of letter names from the first note to the second (including both notes) to determine the interval number.

For example:
- C to D = 2nd (C–D)
- C to E = 3rd (C–D–E)
- C to G = 5th (C–D–E–F–G)

We are working in the Key of C, so no accidentals are involved — all notes are natural.

Step-by-step Analysis

We'll go through each pair:

#### Line 1:
1. C → G
- C to G: C–D–E–F–G → 5 notes → 5th
✔ 5th

2. G → C
- G to C: G–A–B–C → 4 notes → 4th
✔ 4th

3. C → C
- Same pitch → Unison
✔ Unison

4. C → E
- C to E: C–D–E → 3 notes → 3rd
✔ 3rd

5. C → A
- C to A: C–D–E–F–G–A → 6 notes → 6th
✔ 6th

6. B → C
- B to C: B–C → 2 notes → 2nd
✔ 2nd

---

#### Line 2:
7. F → C
- F to C: F–G–A–B–C → 5 notes → 5th
✔ 5th

8. C → B
- C to B: C–D–E–F–G–A–B → 7 notes → 7th
✔ 7th

9. C → C
- Same note → Unison
✔ Unison

10. A → C
- A to C: A–B–C → 3 notes → 3rd
✔ 3rd

11. C → D
- C to D: C–D → 2 notes → 2nd
✔ 2nd

12. C → A
- C to A: C–D–E–F–G–A → 6 notes → 6th
✔ 6th

13. E → C
- E to C: E–F–G–A–B–C → 6 notes → 6th
✔ 6th

---

#### Line 3:
14. F → C
- F to C: F–G–A–B–C → 5 notes → 5th
✔ 5th

15. C → F
- C to F: C–D–E–F → 4 notes → 4th
✔ 4th

16. D → E
- D to E: D–E → 2 notes → 2nd
✔ 2nd

17. D → C
- D to C: D–C → descending, but we count upward: D–E–F–G–A–B–C → 7 notes → 7th
✔ 7th

18. A → C
- A to C: A–B–C → 3 notes → 3rd
✔ 3rd

19. F → C
- F to C: F–G–A–B–C → 5 notes → 5th
✔ 5th

20. G → C
- G to C: G–A–B–C → 4 notes → 4th
✔ 4th

- C to D: C–D → 2 notes → 2nd
✔ 2nd

24. C → G
- C to G: C–D–E–F–G → 5 notes → 5th
✔ 5th

25. C → D
- C to D: C–D → 2 notes → 2nd
✔ 2nd

---

#### Line 5:
26. C → A
- C to A: C–D–E–F–G–A → 6 notes → 6th
✔ 6th

27. F → C
- F to C: F–G–A–B–C → 5 notes → 5th
✔ 5th

- D to C: D–E–F–G–A–B–C → 7 notes → 7th
✔ 7th

30. C → C
- Same note → Unison
✔ Unison
