ハッピーシンセサイザ　君の　胸の奥まで	happii shinsesaiza kimi no mune no oku made
届くようなメロディ　奏でるよ	todoku youna merodi kanaderu yo

儚く散った淡い片思い	hakanaku chitta awai kataomoi
笑い話だね　今となれば	waraibanashi dane ima tonareba
見る物全て　輝いて見えた	miru mono subete kagayaite mieta
あの日々がキレイに　笑ってるよ	ano hibi ga kirei ni waratteru yo

我慢する事だけ　覚えなきゃいけないの？	gaman suru koto dake oboe nakya ikenai no?
「大人になって頂戴ね？」　ならなくていいよ	"otona ni natte choudai ne?" naranakute ii yo
知らない事ばかり　知らないなんて言えなくて	shiranai koto bakari shiranai nante ienakute

ハッピーシンセサイザ　君の　胸の奥まで	happii shinsesaiza kimi no mune no oku made
届くようなメロディ　奏でるよ	todoku youna merodi kanaderu yo
つまらない「たてまえ」や　ヤな事全部	tsumaranai "tatemae" ya ya na koto zenbu
消してあげるから　この音で	keshite ageru kara kono oto de

何の取り柄も無い　僕に唯一つ	nan no torie mo nai boku ni tada hitotsu
少しだけど　出来る事	sukoshi da kedo dekiru koto
心躍らせる　飾らない　言葉	kokoro odoraseru kazaranai kotoba
電子音で伝えるよ	denshion de tsutaeru yo

好きになる事　理屈なんかじゃなくて	suki ni naru koto rikutsu nanka janakute
「こじつけ」なんて　いらないんじゃない？	"kojitsuke" nante iranainjanai?
時代のせいと　諦めたらそこまで	jidai no sei to akirametara soko made
踏み出さなくちゃ　何も始まらない	fumidasanakucha nanimo hajimaranai

「ゴメンね夜遅く　寝るところだったでしょ？」	"gomen ne yoru osoku neru tokoro datta desho?"
「驚いた　私もかけようとしてた」	"odoroita watashi mo kakeyou to shiteta"
心の裏側をくすぐられてるような	kokoro no uragawa o kusugurareteru youna
惹かれあう2人に　幸せな音を	hikareau futari ni shiawase na oto o

ハッピーシンセサイザ　ほらね　楽しくなるよ	happii shinsesaiza hora ne tanoshiku naru yo
涙拭うメロディ　奏でるよ	namida nuguu merodi kanaderu yo
強がらなくたっていいんじゃない？　別に	tsuyogaranakutatte iinjanai? betsu ni
自分に素直になればいい	jibun ni sunao ni nareba ii

何の取り柄も無い　僕に唯一つ	nan no torie mo nai boku ni tada hitotsu
少しだけど　出来る事	sukoshi da kedo dekiru koto
ちょっと照れるような　単純な気持ち	chotto tereru youna tanjun na kimochi
電子音で伝えるよ	denshion de tsutaeru yo
