You have been given a Mizmar
Abu Musa Al-Ash’ari (radi Allahu anhu) reported: The Messenger of Allah (sal Allahu alaihi wa sallam) said to him, “You have been given a Mizmar (sweet melodious voice) out of the Mazamir of Prophet Dawud (alaihi assalam).”
[Sahih Al-Bukhari and Muslim]
‘Mizmar’ in the above Hadith means flute but here it stands for tune and sweet voice. Having a sweet voice is a gift of Allah Who grants it to whom He likes. Blessed indeed are those who are granted this gift and they go about using it to invite people to the religion of Allah.
And Allah knows best!
