Short song arrangement for the orchestra (2m 30s, 84 tactus)

A professional audio track lasting 90-120 minutes is needed for deep concentration, learning, and work. The track should be performed in a modern ambient style and match the level of popular YouTube channels with focus music. Here’s an example: https://www.youtube.com/watch?v=l3vILLA7mXMMain Task A fully finished audio track is required, which includes: atmospheric ambient music; neuroacoustic elements (binaural beats); background textures or noises (if necessary); professional mixing; final mastering. I want to receive a ready-to-use file.Purpose The track is intended for: deep work; learning; reading; programming; writing texts; prolonged concentration. This is not music for sleep and not meditation.Style Modern atmospheric music is required. Guidelines: deep ambient; cinematic ambient; drone ambient; minimal ambient.Emotion The music should create a sense of: clarity; concentration; inner peace; gentle forward movement; open space. No dramatic emotions.Structure Duration: 90 minutes. Structure: 0–10 min — smooth entry into a state of concentration; 10–75 min — maximally stable working state; 75–90 min — smooth conclusion without a sharp ending.Binaural Beats Binaural beats need to be used. I suggest the following structure: 0–10 min — Alpha (10–12 Hz); 10–75 min — Gamma (40 Hz); 75–90 min — Beta (18–20 Hz). If you have experience creating neuroacoustic tracks and can suggest a more effective scheme — I am open to your recommendations.Instruments It is preferable to use: long synthesizer pads; drone; atmospheric textures; light granular effects; spatial reverberations. Very slow changes in sound are allowed.Do Not Use drums; percussion; vocals; words; sharp sound effects; abrupt transitions; distinct melodies; loud climaxes; sounds that may distract.Important Requirements The track must: not become boring even after an hour of listening; not distract attention; not contain noticeable repetitions; sound natural throughout all 90 minutes; be comfortable for listening on headphones.Quality It is necessary to provide: WAV 24-bit; MP3 320 kbps.
