I will describe the high-resolution spectrographs available at the Telescopio Nazionale Galileo (Roque de Los Muchachos Observatory, La Palma). They are HARPS-N and GIANO-B, also combined in the GIARPS configuration, simultaneously covering visible and near-infrared domains. I will also review the scientific highlights obtained since 2012 with these instruments. The access to the TNG is open to the international community through distinct calls. Possible collaborations between SONG and TNG programs are encouraged.
