In elementary school, I played 'Edelweiss' on the recorder.
Unlike a transverse flute, an end-blown flute is held vertically when played.
リコーダー specifically refers to the recorder, a common type of 縦笛.
Standard kanji spelling for end-blown flutes, especially the recorder.
Mixed kanji-kana spelling; sometimes used in educational or explanatory contexts.
Rare kanji form; 竪 is an uncommon character for 'vertical'.
Compound of 縦 (tate, 'vertical') and 笛 (fue, 'flute'). The reading たてぶえ is a straightforward combination.
