This is a study sheet, not an official test or prediction of examiner questions.
Check your instrument/grade/format parameters. Follow current exam-score rules;
the checked piano syllabus prohibits annotations that help answer questions.

STUDY SHEET
Piece and exact edition:
Instrument/grade/format and syllabus page:
Question:
Evidence kind: score observation / instrument explanation / external context
Bar and sign, or source URL/page:
My explanation:
What I do not yet know:
If a demonstration is needed: task planned / actually attempted / result observed
Do not record an unperformed demonstration as successful.

QUESTIONS
1. Explain 4/4 here and verify bar 2's duration.
2. Name the final note's letter, octave and value.
3. Locate the dynamic contrast. Is an exact volume measurement specified?
4. Classify: “bar 3 begins forte”; “an acoustic piano uses hammers”; “Cristofori
   developed the early piano around 1700”.
5. Does that instrument history date this melody to around 1700?

ANSWERS
1. Four crotchet beats in a complete bar. Bar 2: 1+1+2=4.
2. C4 semibreve, four crotchet beats here; first ledger line below treble.
3. p at bar 1; f at bar 3. Relative dynamic directions, no decibel measurement.
4. Score observation; instrument explanation; external historical context.
   Support each with its own evidence.
5. No. The melody is an original SwarShala 2026 teaching example. Instrument
   history cannot date an arbitrary score or establish its musical period.

CHECKED EXTERNAL EXAMPLES
Acoustic-piano hammers strike strings; bridges transmit their vibration to the
soundboard. This is a sourced explanation, not a claimed physical demonstration.

Yamaha attributes the early piano to Cristofori around 1700; this does not date
Window Steps or identify it as Baroque repertoire.
