About this app

Hertz Moon Studio Tools brings together 15 musical tools for guitar, bass, vocals, drums, composition, and audio production. For musicians, songwriters, students, and producers.

**METRONOME, BPM, AND RHYTHM TRAINING**

Practice Metronome lets you set tempo, bar, subdivisions, accents, and swing. Includes Tap Tempo, Speed ​​Trainer to gradually increase BPM, Gap Training with silent beats, and a timer for practice sessions. For guitar, bass, and drums.

**GUITAR AND BASS TUNER**

Chromatic tuner with phone microphone: detects note, pitch, and cent offset. Select the instrument's tuning and adjust the A4 reference. For tuning guitar, bass, and other compatible instruments.

**PENTATONIC SCALES AND IMPROVISATION**

Pentatonic Trainer offers an interactive guitar and bass fretboard, major and minor pentatonic scales, metronome exercises, microphone note recognition, backing, target notes, challenges, and call and response. Practice improvisation.

**AUDIO CHORDS AND CHORD SHEETS**

Audio to Chords analyzes a recording and provides a timeline of chords or individual notes. Ideal for clean recordings of a single instrument; it is not a professional transcription.

Chord Sheet Maker allows you to write lyrics and chords over the lyrics, organize intros, verses, and choruses, transpose the key, listen to chords, and create sheet music that can be exported to TXT, PDF, and ChordPro.

**GUITAR AND BASS TABLATURE**

Tab Maker creates tablature for six-string guitar. Bass Tab Maker creates tablature for four- or five-string electric bass. Insert keys and techniques like hammer-ons, pull-offs, slides, bends, and vibrato; listen to the notes and work with MIDI, PDF, TXT, and JSON exports.

DRUMS, GROOVES, AND MIDI COMPOSITION

Drum Tracks includes a sequencer for rhythmic patterns, swing, velocity, and ghost notes. Create sections like the intro, verse, chorus, and outro, and prepare MIDI arrangements with drums, bass, chords, pads, and melody. Preview and export audio grooves and MIDI files.

SINGING, PITCH, AND VOCAL TRANSPOSITION

Vocal Coach offers guided exercises in pitch, free singing, and solfège: it detects the notes sung through the microphone, the cent shift, and stability.

Live vocal transposer changes the pitch of your voice or instrument in real time and allows you to record the result in WAV format (use headphones).

**SONGWRITING: LYRICS, SYLLABLES, AND METRICS**

Singability analyzes the syllables and stresses of a text to evaluate how the words fit the rhythm. You can use the lyrics alone or add a sung recording to compare the linguistic and musical stresses.

Second Verse compares two verses and helps you determine whether the new lyrics fit the melody of the first, considering syllables, stresses, and, when available, sung audio. For songwriters and lyricists.

**PRACTICE ON AUDIO INSTRUMENTS AND SONGS**

Practice Coach opens music files to practice difficult passages with A–B loops, repeats, slowing down without changing the key, transposition, metronome, and progressively increasing the speed. It supports WAV export of processed practice.

Reverse capture temporarily preserves the last 3, 5, or 10 minutes of audio from the microphone to recover previously played musical ideas and save them as WAV takes, with BPM estimation when possible.

Audio converter converts supported files to WAV or MP3 on your device, without uploading them to a server.

Some tools and advanced features require Hertz Moon PRO, a one-time purchase—it's not a subscription. When ads are added, PRO will allow ad-free use of the app.
