Who it is for
Singers, a cappella groups and instrumentalists who prefer matching a human voice when finding a pitch.
Overview
What Pitch 1024 does
Pitch 1024 answers a request for a pitch with a recorded singer instead of a tone generator. Six voices are available, and a card in the conversation plays the note, the chord, or the starting pitches for a key when tapped.
Several voices can hold a chord together, in stereo or positioned around the listener on headphones, and a progression can be passed along the ensemble a chord at a time. There are also hidden-answer quizzes for notes, intervals and chord qualities.
The audiences named in the record are singers warming up, a cappella groups looking for entry notes, and instrumentalists tuning by ear.
What stands out
The reference tones are sung takes from a cast of six musicians, with an optional spatial mix over headphones.

Where Pitch 1024 is listed
Pitch 1024 is listed in the ChatGPT apps directory only. Kyung-Hoon Kim has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
