Song lyrics
Qu'est-ce qui fait boum quand je reste tranquille ? Je pose la main au milieu de ma poitrine Un peu à gauche, je sens boum-boum Sous ma paume revient un rythme régulier Mon cœur est un muscle au travail Deux doigts se posent doucement sur mon poignet Chaque battement crée l'onde de mon pouls Boum-boum, mon cœur pompe le sang Il se serre, se détend et se remplit Dans les poumons, le sang prend l'oxygène Puis le porte des pieds jusqu'à la tête Je fais quelques petits bonds sans forcer Mes joues deviennent roses et bien chaudes Je touche ma poitrine, puis mon poignet Maintenant, mon cœur bat un peu plus vite Mes muscles ont besoin de plus d'oxygène Boum-boum, mon cœur pompe le sang Il se serre, se détend et se remplit Dans les poumons, le sang prend l'oxygène Puis le porte des pieds jusqu'à la tête Sur le canapé, je me repose Mon pouls ralentit peu à peu Le rythme doux retrouve son calme Boum-boum, mon cœur pompe le sang Il se serre, se détend et se remplit Dans les poumons, le sang prend l'oxygène Puis le porte des pieds jusqu'à la tête Au repos, mon pouls redevient plus lent Mon cœur travaille toujours comme une pompe
Language version lyrics
What taps while I am sitting still? My hand rests near the middle of my chest Just left of center, I feel thump-thump A steady beat returns beneath my palm My heart's a muscle working all the time Two fingers gently rest upon my wrist Each heartbeat makes a wave I feel as my pulse Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head I do a few light, easy jumps A rosy glow comes to my cheeks I check my chest and wrist once more Now every thump arrives a little faster Moving muscles need more oxygen Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head I rest upon the couch and breathe My pulse slows down a bit at a time The gentle rhythm settles down again Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head At rest, my pulse is slow again My heart keeps working like a steady pump
