SWARSHALA — CLEF LANDMARK WORKSHEET
Original learning aid, 3 October 2026
Guide: https://swarshala.com/blog/read-treble-and-bass-clef-landmarks

Scope: written pitches, ordinary treble/bass clefs without octave marks;
no key signature or local accidentals. Middle C = C4. Number lines and
internal spaces from the bottom. A move to the next line OR space is one
neighbouring position. This is a decoding task, not a speed test.

Date: __________  One mistake to investigate: _______________________

REFERENCE (cover this after one practice pass)
Treble G4 is line 2. Bass F3 is line 4.
Treble lines bottom to top: E4 G4 B4 D5 F5.
Treble internal spaces bottom to top: F4 A4 C5 E5.
Bass lines bottom to top: G2 B2 D3 F3 A3.
Bass internal spaces bottom to top: A2 C3 E3 G3.
Treble first ledger line below = C4; bass first ledger line above = C4.

QUESTIONS
Write the pitch, then a short route from a known landmark.
1. Treble: space immediately above G4 on line 2. ____________________
2. Bass: space immediately below F3 on line 4. ______________________
3. Line 3: treble _____________ ; bass ______________________________
4. Treble: first ledger line below the staff. _______________________
5. Bass: space above the first ledger line above the staff. _________
6. Treble: second ledger line below the staff. ______________________
7. Correct this reasoning: "Treble bottom line is E4, so the space
   below the staff is C4." _________________________________________

ERROR LOG
Question: ____  Wrong clef / skipped space / direction / octave
Correct route: _____________________________________________________
One question for a teacher: _________________________________________

---------------- ANSWER KEY: CHECK AFTER YOUR ATTEMPT ----------------
1. A4: G4 on line 2 -> next space up A4.
2. E3: F3 on line 4 -> next space down E3.
3. Treble B4; bass D3. The same position changes meaning with its clef.
4. C4: E4 bottom line -> D4 space below -> C4 first ledger line.
5. D4: A3 top line -> B3 space -> C4 ledger line -> D4 space.
6. A3: E4 -> D4 -> C4 -> B3 -> A3. The number changes between B and C.
7. The space is D4. C4 is one more position down, on the ledger line.
