I refer to an element of Typical Unique HR Melody. While Himesh has given numerous such melodies, according to me, his BEST EVER historic typical unique HR melody pieces that a fan will hear in the pre ABA era are as follows.
From 2.49 to 3.14 - Oodhni (Tere Naam)
The ULTIMATE BEST typical unique HR 'instrumental/vocal' melody piece in the whole of pre ABA era is in between the 1st stanza gap from 2.49 to 3.14 in OODHNI from TERE NAAM, i.e. OFF-DA-HOOK underlying profound heavy drum hits that give KICK, HISTORY male vocals from 2.49 to 2.57 followed by HISTORY quick keyboard flicks from 2.58 to 3.04, followed by HISTORY emotional bansuri piece with halke se feel twists from 3.05 to 3.12 that wins over da listener, followed by majestic heavenly tune from 3.12 to 3.14 that gives KICK.
From 1.26 to 1.33 - Chal Shaadi Kar Lete Hai (Kurukshetra)
Another one of the ultimate best typical unique HR melody 'instrumental/vocal' pieces is from 1.26 to 1.40 in CHAL SHAADI KAR LETE HAIN from KURUKSHETRA.
i.e. OFF-DA-HOOK underlying profound heavy drum hits along with HISTORY instrumental tune from 1.26 to 1.28 & 1.30 to 1.32 with off-da-hook halke se feel twist from 1.28 to 1.29 followed by HISTORY tune from 1.28 to 1.29 & 1.32 to 3.33 that bowls over da listener, followed by Alka's melodious croons along with terrific innocent feel bansuri piece from 1.34 to 1.40
Make a note of the similar thought process of Himesh - the pre ABA composer! In the sense that he decides to use such well structured typical unique HR melody pieces at same spot in between 1st stanza gap, along with underlying profound heavy drum hits and emotional feel bansuri piece to depict that innocence of love (in both the songs - this one and Oodhni).

Start to 0.15 & 5.02 to end - Dheere Dheere Aana (Yeh Hai Jalwa)
