MUSICAL NOTES && INSTRUMENTS ARE MENTIONED IN THE SRIMAD BHAGVATAM:
Srimad Bhagavatam, Canto 1 Chapter 6 Verse 32 states:

SANSKRIT:
deva-dattām imāṁ vīṇāṁ
svara-brahma-vibhūṣitām
mūrcchayitvā hari-kathāṁ
gāyamānaś carāmy aham
Srimad Bhagavatam, Canto 1 Chapter 6 Verse 37 states:
Sūta Gosvāmī said: Thus addressing Vyāsadeva, Śrīla Nārada Muni took leave of him, and vibrating on his vīṇā instrument, he left to wander at his free will.

sūta uvāca
evaṁ sambhāṣya bhagavān nārado vāsavī-sutam
āmantrya vīṇāṁ raṇayan
yayau yādṛcchiko muniḥ
Srimad Bhagavatam, Canto 8 Chapter 8 Verse 26 states:
"The inhabitants of Gandharvaloka and Cāraṇaloka then took the opportunity to play their musical instruments, such as conchshells, bugles and drums. They began dancing and singing along with their wives."
SANSKRIT:
śaṅkha-tūrya-mṛdaṅgānāṁ
vāditrāṇāṁ pṛthuḥ svanaḥ
devānugānāṁ sastrīṇāṁ
nṛtyatāṁ gāyatām abhūt
Srimad Bhagavatam, Canto 6 Chapter 5 Verse 22 states:
"The seven musical notes — ṣa, ṛ, gā, ma, pa, dha and ni — are used in musical instruments, but originally they come from the
Sāma Veda. The great sage Nārada vibrates sounds describing the pastimes of the Supreme Lord. By such transcendental vibrations, such as Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, he fixes his mind at the lotus feet of the Lord. Thus he directly perceives Hṛṣīkeśa, the master of the senses. After delivering the Haryaśvas, Nārada Muni continued traveling throughout the planetary systems, his mind always fixed at the lotus feet of the Lord."
SANSKRIT:
svara-brahmaṇi nirbhāta-
hṛṣīkeśa-padāmbuje
akhaṇḍaṁ cittam āveśya
lokān anucaran muniḥ
