– You have an exceptionally natural gifted voice, wow!; but sorry to say your teacher is pretty terrible and did teach you nothing, nothing at all!!
As a young voice teacher I felt uncomfortable, disappointed: this constant and unanimous feedback on my one, three, two, five years students and no student had that voice arriving, some had also certified issues and yup they disappeared working. Now as a nearly 15 years teaching I realise no compliment could be greater. The technical work we did and do prove itself so functional to disappear into the good function, to be the so difficult to find natural gifted voice. What huge recognition they were, and still are, to our technical work!
My work and research are to have a path to what is structurally and physiologically the natural gifted voice, the rationale underlying this practice has had a paper presentation and two workshops at Pan-European Voice Conference PEVoC14 ( and on some specifics on singing for professionals will be the presented as unique author of other three abstracts at next The Voice Foundation 52nd Annual Symposium.
Knowledge will catch on what is valuable of this path.

I come from a soloist career in classical music interrupted by an abdominal surgery (the surgeon has been convicted for malpractice). I relate to old Italian Belcanto technique because it contains the basis with high refinement tools of a functional and trained voice, for other styles and CCM I have modified and adapted the principles to specific emission requirements, then to some exercises I invented to make a step forward in the possibility of working on voices (here the rationale on them ), other consolidated techniques and practices I studied. I give courses for all styles, since I mostly work on the patterns and functionalities of the voice and their use in the repertoire. I have results credited by career improvements, issues solved, from no voice to great natural voice in beginners and amateurs, in vocal issues of organic and functional origin, called by their doctors or speech therapists. These last are objective results on singers and not singers, with issues not solved by training or therapies of excellent level, the effect of which were the transforming career or simply easiness and freedom of communication in mundane life, here the page dedicated

We work in a very individualised way, and in a more generic by little classes, on fundamental abilities and functions of voice production. Those are the same for all styles and they are more or less actively used depending on style, voice classification, level of training or of development, age.

My credits are mostly objective: the massive changes in career trajectory of all the professionals or not yet professionals. If you like to read some from some in the image gallery above you find some, as the thanks for our work in the cover of Surya of international jazz singer Eleonora Bianchini.

Yes I have a master Conservatory degree in Classical Soloist Voice, I studied with some italian relevant voice teachers as Giannella Borelli, Anna di Stasio and Giovanna Canetti and attended courses and masters from jazz to chamber music and popular music or contemporary, and I didi sing in national and international Festivals and seasons.

If you have voice issues there is a low cost program to help you, it is the cossuprogram. For practical infos write me or get to the FAQ. I am happily returning to sing something since my health issues are in remission.
My courses are available everywhere online, in person in my studio in Liège (Belgium) in English, French or Italian. Write to me at, click on this link to have informations about my courses and how it works practically

Professional students

Those are some of the professionals that are and have been my students.

Eleonora Bianchini 

Weekly student 2016/ 2019, now just a little control of the stabilisation a couple of times per year. Singer and composer, ranked 4th Best female Italian voice for  2016, graduated and merit scholarship at Berklee College of Music in Boston, Conservatorio Morlacchi and Santa Cecilia in Perugia and Rome (Italy), international collaborations (Oscar Stagnaro, Rosa Passos, Eva Ayllon at Carnegie Hall, Lincoln Center and Queens Park in New York as well as Latinoamericando Festival in Milan and Fiestaroma in Rome Walker, Jamey Haddad, John Pierce, and has also recorded for Danilo Perez’s Panama Suite Big Band projectPortinho, Klaus Muller, Felipe Salles, Hector Martiñon, Juancho Herrera, Aquiles Baez, Leo Traversa and many more. She has a stable duo project with upstanding italian upright bass player Enzo Pietropaoli, they record for the label Fone Jazz Records.  We worked on a weekly basis for 18 months to make a deep technical work, and we obitained what was on purpose: her 5th cd produced during our work is now distributed by national stores laFeltrinelli, national radios called her to sing live (Rai24, Rairadio1, LaRepubblica web) and Rairadiorai transmitted an old concert in Ecuador. We had to work on technical solutions she was used to but not accorded to the nature of her voice, reshaping the way to look for solutions (perhaps the most difficult task with a professional singer), so freeing a hidden capacity of some characteristics she thought where just nature in some. Thanks Eleonora, and your thanking me in cd cover.  It has been a great pleasure and honour to work and shape different coordinations of your voice and your trust in me in doing so, so happy of this cd and the new repertoire and finally with big band and further. She knows I am pushing her a bit to do more and more; she is such an incredible musician and I still dream of what I have heard in class, just waiting the time she can realise this new project.

Here all news and info on her and her concerts and projects

A talk with her on our lessons and cossumethod 

Elena Paparusso 

“Privately I had the luck

of studying with the alto Lucia Cossu,

who has been a keystone in my technique. “

Elena Paparusso

Jazz singer, we completely transformed her way of thinking voice and singing in a intense period of 6 months and then a regular weekly basis for another year. You can see part of this evolution in a video here

The results were that finally started a true carreer:  her first CD Inner Nature, winner at Winjazz competion 2015, many more gigs, an european tour, in november 2017 she opened a concert of italian popstar Elisa for Save the Children. Elena was one of those singer with an extremely musical attitude and the final setting of her voice is something composed by an absurd well balanced work of proper muscles of appoggio and sostegno in positions not usual for a coloured mezzosoprano as she is. We made a well sorted absurd in which she has a colour of overtones on which she loves to relate and work on, and just leaving the shades of the mezzosoprano but not the full sound, the velvet redistributed as a vibration round the attack in all the tessitura ’till the high notes. It is something very peculiar and perhaps very contemporary for italian jazz scene, and we could obtain something she did not think she could achieve even if she was dreaming about since she started singing.“>

All news about her and her beautiful album here 

Elena Paparusso Noci intervista



Galil3o, artistic name of Francesco Galioto is my weekly students since september 2017. He is a guitarist, singer and songwriter from Rome (Italy). Rewarded by critique prizes, sung at the national show Sanremo Giovani and at the Concerto del 1 Maggio (both worlwide broadcasted by RaiTV), opening concerts of important italian popstars as Gianluca Grignani and Marlene Kuntz, playing in the most important venues of Rome (Orion Club, Stazione Birra, Circolo degli Artisti, Piper club, Jailbreak). Previously in the FSH band as composer, singer and guitarist now has a soloist project the Galil3o. I am just giving him some technique easyness and skills to have him more singer than songwriter, trying to change nothing of his way of singing. He was excited and happy of what he could do while recording just after a couple of months of work together.

During our work he recorded his first solistic songs, won the Spaghetti Festival 2018, reached his first national radio RAIRadio1 experience, published his first soloist album that is encountering great success.

All things him here
Volevo fare un disco

Eddie Monroe

Intensive work April/September 2018. Great songs and personality, not great technique but a huge potential. In few time he followed me so well. I have been kind and tough, truly tough where required on some old bad habits. Bad habits have a special place in my work because they have a bad order in the brain and a great part of our work is to solve bad roots that you pay too much. He trusted and followed me and now he is ready for his beautiful original songs in a great discographic project, a project born on his songs and voice just started between London, Sicily sand New York. To me he is still a bit too high in the larynx but it is now a question of time to gain stamina and a bit more relaxation in the connection, but yes truly good work.  And yes we have the medium voice he had not, good good job Eddie. What a pleasure and honour to be the vocal reference for those artists who arrive to me.

Enjoy just few seconds of his song during one of our lessons.


Margherita Rinaldi 


Weekly session 2017/2020. Singer, graduated in vocal jazz from Saint Louis College of Music and Conservatorio Santa Cecilia in Rome (Italy). She collaborated with pop, jazz, rock, blues, latin, reggae groups as soloist and backing vocalist, and two stable collaborations in Quarteto Malandro and BMVCabrio. In 2018 her debut album, always in 2018 she wins the audition for Emanuele d’Urso swing orchestra, some new collaborations, a new project. We are going towards her goals.

Light voice, we are working into a technical research to a personal effectiveness in her sound to support the mixture of electronic and brasilian mood of her musical soul.

All things her



Alice Robber

“When I used to write

I always foreseen, I always judged myself because

I do not know. May be I wasn’t, I don’t like while I was singing

or I felt myself not precisely or I do not know.

But now

when I hear myself, when I record myself  I feel that it is not perfect or whatever,

it’s what I want. “

                            Alice Robber

Alice Robber, artistic name of Alice Pistoia. We made a series of our technical full immersion in October and November 2018 in London, few months after she releases her first song and video. The series have been initially streamed on Youtube (where it had remained available for some months) to give a truer flavour to our work and the pressure (useful to speed a change and motor control adaptations) that the public always give to an artist, then it was correct to move further.

Here the playlist of our intensive work

This is the post dedicated Alice and me the series some others clip on Youtube and Instagram #aliceandmetheseries  #aliceandme #alicepistoia



Chiara Morucci

Singer, composer winner of many awards and well established career. We made some five months of regular sessions to clarify some technical points in theory and perspective.

Laura Sciocchetti

Roman jazz singer, she came for some issues in the voice that made her not have comfort and colour of her deep and strong chords without a lot of struggle. We solved the issues in some months of intense work in 2015, she could win the vocal competition Lady Day 2015 for Ancona Jazz. She became in 2017 soloist for the Italian national jazz Orchestra of Conservatori. 

Lorena Falbo


A short intense tune up of four months. Soul singer, winner of the 2010 Festival Estivo. First are two original songs in 2011, after four months of work together. You can hear the difference from the precedent. We gained ease in high register , the possibilities of more dynamics in medium register, pianissimi and a differently coloured high register, more ease in high and heavy rhythms. During those months she could place in repertorio Oggi sono io in the Mina version, some other difficult songs of Mina and some standards she immediately sung in Rome venues.

At the end of our work 

Before our work 


Gianluca Grossi

Songwriter. Short and intense tune up for his debut concert in Piper club in Rome in 2011. We could work on the roots of some defaillant vocal gestures, and it was a proficous work.


Roberta Limoncelli

My student since a couple of years, now she can be presented officially and she will have a place between the professionals since she has been hired for a show in which they are just two on scene dancing, acting and singing (mostly singing) and she has been proposed for a weekly gig at her name.

Now you hear her potential and yes she is pretty something. She sings in a precise Italian song style. Enjoy a little minute of the today lesson

Here she talks about the show

Not professional students

Some of my students.

6 years lessons amateur student Eleonora 

Eleonora Braconi

Eleonora is a young singer, composer of some songs, my student for a complete course when I let her go as our work was completed. Weekly lessons from 2010 to 2016. Here you can listen a demo with some covers. Enjoy, she is pretty special.

2 years lessons amateur student Agnese Agnese Piola

Weekly student 2014/2017, now a monthly session. She arrived with a technical problem that made here not being well in the pitch and a too much air in the sound. We worked just technically for 18 month and then I could convince her, who always refused, to perform in a class Recital. This is her first demo recorded in three hour in autumn 2016 after the summer pause. She is now involved in composing her first songs,  she is in a band, they are looking for a producer.


2 years lessons semiprofessional student Rita  

Rita Negrini 2

Rita is a young singer, my student  October 2015/ December 2017. Great personality, great voice, she sings since she is very young. We have worked to start giving her a voice for a career, she is now understanding if she wants to put into this project true commitment and daily energies.


3 years lessons amateur student Giorgia 

Weekly student 2008/2011. Winner of some singing competitions, she participated to tv shows for teen singers and has been called to open concerts for professionalson a regular basis, she sung the song closing the show at the Christmas concert of teens 2011 for Sky. We worked on italian repertoire (Elisa, Laura Pausini, Mia Martini, Claudio Baglioni) and international (Sara Bareilles, The Beatles, Elton John,Withney Houston, Amy Winehouse, Robbie Williams and others).
Here when she was 15.

2 years lessons amateur student Irenea 

@Irenea__ Listen to her here  

and here the audio during an online lesson singing with an exercise that wants a pen being hold horizontally between her teeth while singing and not let it fall for all the song. 

Another happy ending from struggle. She arrived to me not being able to sing without strain and breaking the sounds. Younger she was a natural voice, then some voice lessons and her voice did not improve but collapsed (that is why training of young voices must be of the finest level of knowledge for functionality and voice development, so easy to slip down fast and put dysfunctionality just for too much pretension too soon). It developed in a dysfunctional voice with struggle and breaking the sounds, impossibility of singing more than half an hour every other day.  Logopedic treatments and other different voice teachers useless. She did not contact me immediately because skeptical of Skype lessons. Then we started, we made 11 months weekly lessons, a pause of one year due to her scholastic tasks. Another 11 months of weekly lessons and here she is preparing the first gigs, no need of my lessons now. She seems to develop in a talented professional, now it is her choice and path, but not anymore struggle for unknown reasons. Very very happy.

Now you can hear others improvements few months later and in her Instagram
